An infrared thermometer (IR thermometer) is a handy tool that measures the surface temperature of objects without making contact. You simply point it at a pan, grill, or piece of food, and within seconds you know how hot the surface is. This makes it incredibly useful for checking hot cookware, frying oil, pizza stones, or even oven hot spots. But here’s the big question many home cooks have: can a digital infrared thermometer for cooking measure the internal temperature of meat and ensure food safety? Let’s explore this in detail.
What Is an Infrared Thermometer?
An infrared thermometer is a non-contact device that measures the surface temperature of an object by detecting the infrared radiation it emits. Unlike traditional thermometers that require physical contact, infrared thermometers allow you to check temperatures from a distance — instantly and safely.
For cooking, this means you can measure the surface temperature of a cast iron skillet, a pizza stone, or even hot oil without sticking anything into it. It’s quick, hygienic, and especially helpful when dealing with extremely hot surfaces.
Can You Use an Infrared Thermometer for Cooking?
Yes, absolutely! Infrared thermometers are perfect for specific cooking tasks, though it’s important to understand their limitations. Many infrared thermometer only measure surface temperature, they are not the best choice for checking the doneness of meat on their own. However, they shine when it comes to checking cookware and ingredients where surface heat matters.
Great Uses in the Kitchen:
- Grilling & Searing: Want to know if your skillet is hot enough for that perfect sear? An infrared thermometer gives you an instant reading.
- Pizza Making: Checking the temperature of a pizza stone ensures it’s ready for crispy crust.
- Candy Making & Baking: Infrared thermometers help monitor the surface of sugar syrups or melted chocolate.
- Oil Frying: Safely measure oil temperature without risking splashes.
But what about when you need to check internal temperatures, like making sure your steak is medium-rare or your chicken is fully cooked? That’s where a dual-function infrared thermometer comes in.

Tips to Use an Infrared Thermometer for Cooking
Here’s a simple guide for getting the most out of your infrared thermometer:
1. Know What You’re measuring: Remember, infrared thermometers measure surface temperature. For meats and baked goods, check internal temperatures with a meat thermometer. For convenience, you can use the ThermoPro TP420 to measure both the surface temperature and internal temperature.
2. Keep the Lens Clean: Dirt or grease can interfere with readings. Wipe it occasionally for accuracy.
3. Mind the Distance-to-Spot Ratio: The farther you are from the surface, the larger the area it measures. For accuracy, stay within the recommended distance.
4. Use for Hot Surfaces: Cast iron pans, griddles, ovens, and stones are perfect candidates.
