A Comprehensive Review of the Best Instant Read Thermometer

A lot of us, home cooks and even professional chefs, have a hard time “eyeballing” or estimating the temperature of food, especially when grilling. Grilling may seem like a simple lunch activity, but roasting a thick slab of beef or a fat pork brisket is more complicated than you think.

When cooking in an open fire like a bed of charcoal, you cannot control the heat, so you do not know how the inside of the meat is cooking. Luckily, a good instant read thermometer can perfectly tell you when your steak is already nicely seared!

An instant-read thermometer is a thermometer with a metal probe that is usually 4.5 inches long. It records the temperature of the food in a couple of seconds. Just like your brisket knives and pans, quality and a reliable thermometer is always worth buying, no more wasting a good piece of rib-eye or filet mignon by overcooking it or risking yourself to salmonella because of undercooked chicken!

1. Thermapen Mk4

Thermapen Mk4While this list is not ranked, the Thermapen Mk4 is first on this list because of how fast and accurate it is. It can provide an actual temperature reading to ±0.7°F in just two seconds. This is the right choice if you are overseeing a fast-paced kitchen.

A good thermometer is an intuitive thermometer. First, the Mk4 has a rotating screen to show the display whatever the orientation of the thermometer’s body is. This way, the reading is shown on any angle. It also has an automatic backlight — no need to grab your phone’s light to see the temperature.

Lastly, it has a native motion sensor. The thermometer will automatically turn on when you move it and turn off if left unmoved. This feature will also help to save battery. It is powered by a single AAA lithium battery, which is marked to have a battery life of 3,000 hours.

A durable polymer body houses the electronics inside. Meanwhile, the metal probe snaps shut on the body. This technique avoids unnecessary snagging and any accidents given the probe’s sharp tip.

Checking the temperature has never been this quick and easy. Using this is an excellent start to streamlining your kitchen workflow with an impressive IP67 waterproof rating. This one is going to withstand the stressful demands in the kitchen.

The Thermapen Mk4 is the 4th reiteration of the model. You know the company listens to its customers when they regularly upgrade a product that is already a staple in both professional and casual kitchens. The brand has a loyal following from casual cooks to professional chefs. Its overall aesthetics will tell you that the thermometer is made for its customers and not just for sole profit.

It comes with a two-year warranty, which is usual for thermometers this price. Also, when you buy it brand new, there is a certificate of calibration in the box. It shows the result of a calibration test like the test temperature and what the thermometer recorded.

Pros
  • Despite its price, its speed and accuracy is comparable to thermometers above its price range
  • Auto-sleep, auto-on, and auto-rotate keeps everything hassle-free
  • Foldable probe for safety
Cons
  • No hole on the body for an attachment to keep it
  • Bulky build profile

We do not want to spend our hard-earned money on kitchen equipment that is just gimmicks. The Thermapen Mk4 is an essential tool that shows you are no longer a casual cook anymore but rather an enthusiast!

2. ThermoPop

ThermoPopKeep it light and fun with the ThermoPop: a pen-like thermometer with a design as good as its function.

You can stick the probe up to 4.5 inches, which is long enough to dig deep into thick meat, an important aspect when roasting a pig’s leg. The temperature is in degrees Fahrenheit and rotates to whatever angle you are using it by clicking the button. The backlit screen will also avoid misreading the temperature.

Despite its small size, it has a high-temperature range for high-heat operations. This product can be your only food thermometer for making a sourdough loaf to even Beef Wellington. It is as capable as “serious” thermometers available in the market.

For those looking for the best “bang for the buck” thermometer, this one cannot be beaten. It is just significantly faster and accurate compared to other thermometers in its price range. This product is also a perfect tool in your home kitchen without the need to shell out lots of dollars to get a reliable and crowd-favorite thermometer.

The body is a circular plastic that resembles a lollipop, hence the name. ThermoPop, vs. ThermaPen Mk4, can be stored in its cover, which you can clip on your shirt. You need not worry about repair as it also comes with a two-year warranty. Overall, the ThermoPop is the top pick of Wirecutter, a leading review website.

Pros
  • Small size but still an accurate thermometer
  • Affordable price, and can buy multiple of this for your staff
Cons
  • Too basic for more complex operations
  • Build quality does not inspire confidence

As said earlier, a probe thermometer is not a replacement to a leave-in thermometer. Instead, both are used together usually. The ThermoPop is a thermometer small and light enough to keep attached to your uniform all the time. Overall, it is hard not to recommend this thermometer.

3. Javelin PRO Duo

Javelin PRO DuoIf you already own a probe thermometer and want to upgrade, the Javelin PRO Duo is a good start. Just by looking at it, you know it is already meant for serious cooking.

To begin, this feature-packed thermometer is designed for long-term use. It has an IP65, which makes it splash-proof (this is different from submerging the item). The 4.25-inch probe is specially made from 18/8, food-grade stainless steel. Indeed, it is a professional thermometer for professionals.

However, what makes this thermometer a cut above the rest is the Intelligent Stabilization feature it has. Above a live fire, a food’s temperature will fluctuate. The thermometer will get the average temperature for you.

It has a minimum and maximum temperature of 40°F and 482°F, respectively. Meanwhile, the error margin is just at ±0.9°F and can quickly and accurately deliver results in two to three seconds.

The thermometer will also ring an alarm you if it reaches a specific temperature. The other feature it has other thermometers do not have is it can display the minimum and maximum temperature of the food you are cooking.

Even in the build quality, the thermometer is an upgrade to others. The plastic used feels durable, and the screen is clear. Even the hinge that pops up the probe is not made with cheaper materials and shoddy engineering – something that a lot of cheap thermometers do.

The best part here is that this thermometer can also be magnetized to your refrigerator’s door. You do not need more scrambling in your cluttered drawer to find it. It can also be attached to a carabiner. The 4.5-inch probe can be folded shut to avoid injuries. And since it is meant for industrial use, the two-inch display does not just auto-orients itself but is also anti-fog.

While it is a midrange thermometer with robust construction, you should not let it lean on a heating pot to record the temperature of the content. It might melt the body and ruin the electronics.

Pros
  • Long lifespan thanks to its IP65 build
  • Intelligent Stabilization feature does not make you guess temperature in case of fluctuation
  • Large, anti-fog, and easy-to-read two-inch display
Cons
  • No physical buttons
  • Price is not entry-level

In terms of build quality, level of accuracy, and feature set, the Javelin PRO Duo is a serious contender for the number one thermometer in and even above its price range. It is marketed towards home cooks who actively practice cooking and chefs in small restaurants. This product is a thermometer longer compared to the first two on this list.

4. Maverick PT-100

Maverick PT-100The Maverick PT-100 is an industry-standard thermometer that is rugged, both form and function. It is double the price of the thermometers mentioned above in this list for a reason.

First, it is a National Sanitation Foundation or NSF-certified. Its accuracy is also certified by the National Institute of Standard and Technology. It is an accurate commercial-grade thermometer that can last the rigors in the kitchen!

Further, this product is only IP44 and not IP65. It is only splash-proof but may receive damage from water streams coming from a nozzle. It is also shock-proof, meaning it can withstand multiple drops on concrete, which is a usual case in professional kitchens.

The probe is 5 inches, which means that it is longer than most thermometers on this list. It uses a type K thermocouple with a micro-tip probe just like all thermometers in this list.

Aside from the LCD, it has a conversion table of Fahrenheit and Celsius values. Given the certifications this temperature, it is safe to assume that this one is intended for international customers or chefs who might be cooking in countries oriented to the metric or imperial system.
The battery indicator is helpful too. You do not want to be preparing for a family feast and have your thermometer lose charge in the middle of it.

It uses 3 AAA batteries, so expect a long battery life and easy replacement. When you hold it, it has a heft to it and feels solidly engineered. Its size is also perfect for gripping on – not too small that it might slip out or too big that it can be fatiguing.

Whether you are a professional or enthusiast, you will appreciate a thermometer that is rugged, industry-approved, and accurate. A food will undergo a lot of changes when exposed to heat, knowing the precise temperature will help you control what meal you will serve to your customers or family.

Pros
  • Certified by two international standards organization
  • Digital instant read thermometer that is also rugged
  • Made to be used for commercial use – fast-paced, big batch cooking
Cons
  • Does not turn on automatically
  • Requires at least three batteries

Those interested in the Maverick PT-100 are probably experienced already with probe thermometers and high-quality kitchen tools. However, if you are a first-time buyer, it is also wise to invest in a professional thermometer. After all, we all want our food to come out tasty for everyone to enjoy.

5. ThermoPro TP19

ThermoPro TP19There are two reasons why the ThermoPro TP19 is one of the best-selling thermometers in the market: it is waterproof, and it is half the price of thermometers with the same feature set. You can wash not just the probe but also the body.

It has the usual features most digital thermometers have. It also has a rotating display for weird angles and an ambidextrous body to accommodate left-handed customers. The best part is it can give you the final temperature in 3 seconds max with a margin of error at ±0.9°F or ±0.5°C.

The motion sensor also reduces the steps in using this by opening, sleeping, and shutting down automatically. It automatically sleeps after staying put for 90 seconds and powers up immediately the moment it is moved. It can also be magnetized on metal surfaces, which avoids losing it during fast cooking operations.

The two-inch display is a pleasure to look at. It does not glare much that you cannot see what is displayed. It is also sharp when you look at it from different angles.

If you are a barista that wants to achieve minute perfection up to the last degree in your water and the coffee itself without breaking the bank, this is the right choice. Also, it has a lock function, so the probe cannot spring out accidentally and poke someone. A useful feature if you are always bringing this with you.

There is nothing more to say as all its features say it all. This product is a simple and affordable thermometer that works excellent in the kitchen. We will be surprised if you can find a cheaper thermometer with the same level of design and functionality as this one.

Pros
  • Reliable waterproof and affordable
  • A lot of user-friendly features that speed up your workflow
  • Can be magnetized to your refrigerator or kitchen door
Cons
  • Feels bulky and awkward to grip
  • Stuck with Fahrenheit

Are you looking for an excellent entry-level thermometer that has enough features to speed up your cooking but not too packed to complicate it? The ThermoPro TP19 is a solid choice as a first or backup probe thermometer. With its high price-to-value ratio, it is obvious why a lot of people are swearing by this tool.

6. Cooper Atkins DFP450W

Cooper Atkins DFP450WIf another family member loves to help around in cooking, the Cooper Atkins DFP450W is a bright yellow thermometer that has some extra features to improve your kitchen experience.

The thermometer might look more “fun” compared to its competition, and it does not lack certifications. It is certified by the NSF, Conformité Européenne (CE/European conformity), Waste Electrical and Electronic Equipment (WEEE), and Restriction of Hazardous Substances (RoHS). Not just a capable tool but also a safe one for you and your family.

The best thing about this tool is its temperature alarm. Set the temperature you want, and when it reaches that particular temperature, the visual alarm will blink. Of course, you should not use this inside the oven but on stovetop operations only. This product will avoid overcooking or even burning of the food. This mode is a feature that differentiates a good thermometer from a great one.

It also has a lifetime warranty. Yes, most items with lifetime warranty have a lifespan of more than five years. Thanks to its IPX7 waterproof rating (can be submerged up to 30 minutes underwater up to one-meter depth), this item will last long in your kitchen despite daily use.

It also has an Accurate for Life guarantee. Meaning, you do not need to worry about your thermometer going faulty all of a sudden.

However, it is not the fastest nor most accurate thermometer. Its margin of error is ±2°F and delivers the reading after 5 seconds max. Other thermostats in this list have a maximum response time of three seconds and a margin of error of ±1°F. Also, compared to other thermometers on this list, the display on this is on the top.

With a lot of certifications and features, it is obvious why this thermometer is quickly becoming a best-seller in online stores.

Pros
  • Lifetime warranty, IPX7 waterproof rating
  • Temperature alarm will avoid overcooking
  • Lots of certification from standards organizations
Cons
  • Slow response time
  • Not professional-looking

Cooking at home does not require a down-to-the-decimal precision most of the time. However, what is needed is a thermometer that is safe, durable, and has an alarm. Most home cooks have other things going on aside from cooking, so a warning is necessary.

7. ThermoPro TP03

ThermoPro TP03When talking about the best instant read thermometer, people usually associate price with quality. The ThermoPro TP03 is here to prove you wrong. It is a slim thermometer that you can put in your bag or pocket.

It is priced below 30 USD but has the same functionality (and even more) with other keyboards in this list and above its price range. If you are frustrated with thermometers that let you do the conversion from Fahrenheit to Celsius or vice versa, this thermometer will quickly convert it to you with just a click of a button.

The temperature range is from -58°F to 572°F. The accuracy is marked at ±0.9°F for temperature 32°F to 212°F. The probe length is short at only 3.9 inches and made of food-grade metal. A thermometer of this value will be used for regular meals, so a more extended probe is not necessary.

This product is the right choice if you have multiple staff or even teams involved in the kitchen. Buy one for each, and there will be no reason for them to undercook or overcook a dish. You can also buy in bulk and get a discount.

Just like the ThermoPro TP19 mentioned above, it is a value thermometer for those looking for a simple thermometer for simple cooking. It is a straightforward thermometer with an accessible price.

Pros
  • Truly a value thermometer
  • Dedicated Celsius to Fahrenheit conversion button (with an accompanying conversion chart)
  • Up to 3 years warranty
Cons
  • The body does not feel as robust when held compared to the TP19
  • No lock feature and backlight

People will buy this as their first thermometer, a backup, or a quick replacement for your first thermostat. It does what a thermometer needs to do without the extra features that ramp up the price tag.

8. Habor 022 Meat Thermometer

Habor 022 Meat ThermometerCooking steak is an art. An 80-dollar piece of meat can be made into a delicious and juicy steak. There are times where we do not adequately heat the pan that when we sear the meat, the insides get cooked too. The Habor 022 Meat Thermometer will save you from ruining your steak.

While it takes extra time to deliver the final temperature, it makes sure you get a precise reading. A piece of meat does not react uniformly. Even if you already have years of experience of cooking steak, you still need to use a thermometer to check.

It can measure temperatures from -58ºF to 572ºF(-50 °C ~ 300 °C). Usually, steak is cooked at 160ºF to eradicate any food-borne bacteria without cooking it throughout thoroughly. There is a button to convert from Celsius to Fahrenheit and back.

A pen-like case encases the 4.7-inch probe. The overall silhouette looks premium – from the silver body, clear font, large display, and jet black case. The case’s clip and keyhole also help in storing and handling the item.

The Food and Drug Administration also approves it. Important for tools that are regularly in contact with food served to people.

Could this be the best instant read meat thermometer in its price range? You can only know if you try it. You cannot go wrong with this one. With its CE certification. 45-days money-back guarantee, and 18-months warranty, it is a smart purchase for less than 20 dollars.

Pros
  • Premium look, affordable price
  • Wide temperature range
  • Long 4.7-inch probe
Cons
  • A bit slow to deliver results
  • The texture of the body can be slippery when held with sweaty hands

Weekend barbecue parties and steak nights should be no problem with the Habor 022 Meat Thermometer. Even if you do not regularly use a thermometer, this one has a wallet-friendly price. Also, if you are maintaining a clean and modern looking kitchen, this one will not break your space’s aesthetics but rather complement it.

Why Should You Invest in a Good Instant Read Thermometer?

Simple – because it is not 100% accurate when you eyeball a food’s internal temperature even if you slice it up. Food’s chemistry changes a lot when exposed to heat. For example, a cooked egg has 180% more protein content than raw eggs.

When making bread and pastries, the thermometer inside only measures the external temperature. You need a probe thermometer to know how hot is the inside of the food.

Also, it is proper training for budding home cooks. If you regularly use a probe thermometer and usually cook a particular dish, you will know the internal temperature just by looking at the outside of the food. Eyeballing a food’s heat is a risk that requires years of skill and experience before you can master.

If professional chefs still use a probe thermometer every day despite their training and experience in the industry, you should too!

Instant Read Vs. Leave-in Thermometer: What’s the Difference?

Instant Read Vs Leave-in ThermometerInstant read or probe thermometers is used when you want to measure the temperature of a mood immediately. This item is suitable for cooking a slab of steak since it records the internal temperature, not just the external. You will know its doneness without slicing it up only by using an instant-read thermometer.

It also has a faster response time, right for a kitchen that is serving 20+ plates every hour. Also, its temperature range is narrower compared to oven thermometers. After all, an instant read thermometer is meant for stovetop operations and quick checking, not long-term measuring.

A leave-in thermometer is used for long-term cooking, usually in a BBQ smoker or an oven. Let us say you are smoking a brisket for four to five hours. Unless your smoker has a built-in thermometer inside, you will need to use a leave-in thermometer to monitor the temperature in real-time.

Since it will be left inside an oven or a pot, it is not made of plastic but usually of glass. It is not digital since the heat will fry the electronics inside. It looks like the speedometer of a vehicle.

Of course, it is slower to read the temperature than the probe type. You can use both since each has a different purpose, but for the beginner home cooks, better to still use a leave-in thermometer. Not that you will monitor temperature, it will also train you how a particular food reacts and look like at a specific temperature.

We recommend owning both. Use the instant read for cooking steak on a pan and the leave-in for baking brownies. Also, make sure you always check the accuracy of your thermometers over time. Try to measure boiling or ice water with a separate thermometer and see if both get the same reading.

What Makes an Instant Read Thermometer Good?

Here are some characteristics of a quality instant read/probe thermometer:

1. Accurate

A probe thermometer should have a maximum margin of error of ±2°F. Of course, leave-in thermometers are more accurate since it measures the temperature in real-time. A probe thermometer delivers acceptable readings (especially internal temperature) in a short time.

While almost all thermometers have a temperature range from ~40°F to 500°F, you must test it. For cooking that involves higher (or lower) temperatures, such as using a brick oven, you are better off using a dedicated oven thermometer.

2. Fast

You should not wait more than five seconds to find out the temperature. If it takes too long, it might be that the temperature inside is fluctuating, and the thermometer cannot get a final value.

While we usually recommend to let the thermometer stay probed inside the food for a few more seconds for accuracy, thermometers now are capable of delivering results in just three seconds — an essential feature in a restaurant serving 50 plus people on peak hours.

3. Robust and safe

Your thermometer must be up to the standards of specific organizations that deal with food-grade materials. You will be probing the thermometer into the food regularly, and the thermostat will be exposed to heat. There might be injuries if you buy a cheap one with the questionable build quality.

If you are a home cook, no need to buy thermometers that are water and shock-resistant, given the mild environment of a home kitchen, of course, it will help, but your money is better spent elsewhere than a feature you do not need.

4. Intuitive

When you are under time pressure and handling multiple dishes, your tools should not hinder you but assist you. Features like auto-power and auto-rotate will help you a lot by reducing the steps to get a final value.

Another thing you should consider is the display. A slight misreading of the temperature can be the difference of an award-winning meal to a highlight of a criticism.

5. Reasonably priced

This dilemma is usually what makes us decide if we are going to purchase a specific item: the price. Of course, your expectations of a thermometer’s capabilities should be based on its price range. However, all eight thermostats here offer a functionality that is found even in thermometers double its price range.

You should not pick the cheapest one but rather the one with the best price-to-value ratio.
