The Differences Between Thermopop and Thermapen

After presenting the most popular instant-read thermometers of Thermoworks, you might be wondering what would be the better purchase for your home cooking.

The Thermopop and the Thermapen will be assessed by the following differences to get you what you need at your very own kitchen:


The Thermapop is shaped like a balloon and has a case for safekeeping when not in use. It has a thin probe, in which you uncap and insert into the meat to read its internal temperature.

It also measures 7H x 1.8W x 0.8D inches. The mold-in seals and the buttons help make the device water-resistant.

On the other hand, the Thermapen measures 1.97H x 6.2W x 0.75D inches (50H x 157W x 19D mm). It has an excellent structure and grip that is reliable in avoiding slips and accidents when cooking.


The Thermapop display should be turned on and off by the user. It also has buttons for rotating the display. It has significant backlight digits that are easy to read.

After 5 seconds of the display, the reading will be at 1° during the final reading. It rotates in for directions, which are helpful in reading at any angle.

On the other hand, the Thermapen MK4 boasts a patented auto-rotating display. It displays an intuitive backlight that adjusts to the brightness or darkness of the environment. Thanks to its sensor for this intelligent feature! Both of the devices, however, can be switched from degrees Fahrenheit or degrees Celsius easily.


The Thermapop display has an accuracy of ±2°F to 248°F, while a Thermapen has an accuracy of ±0.7°F (±0.4°C).

To check the efficiency of your Thermopop thermometer, you can try an ice bath test at home. The ice bath test starts by filling your vessel with water and ice (you can use ice cubes or crushed ice).

Then, add water just enough to cover the ice. Next, insert the probe and swirl it as you do so. Your Thermopop should read 32°F (0°C) in the ice bath. This shows that the Thermopop is also reliable and accurate in giving temperature readings.

Meanwhile, the Thermapen MK4 has a professional-grade accuracy in an instant. Meaning if you are grilling a steak while in the grill, you can take it off right after you temp it to avoid overcooking.

To verify your accuracy with a Thermapen, you should insert the probe in different parts of the meat. The thickest part of the meat is where you can test the accuracy of your Thermoworks Thermapen MK4 and see how reliable the results are.


The response time of the Thermoworks Thermopop is 2 to 3 seconds. This feature is perfect for those who want to safely serve food on the dinner table at home without overcooking it.

Ignition temperature or the ignition point sometimes called the kindling point of a substance, pertains to the lowest temperature a combustible gas will ignite and sustain combustion in a typical atmosphere.

The Thermopop ranges from the lowest temperature at -58°F up to its highest temperature of 572°F. This feature means that it can be used in frozen food or an ice bath test.

Meanwhile, the Thermapen MK4 calibrates from its lowest point at -58.0°F or -49.9 °C and at its highest point of 572.0°F or 299.9°C. Its ignition points along with accuracy and speed make the Thermapen MK4 an unbeatable tool for the professional cook and chef!
