Best Infrared Thermometers for Your Kitchen

Whether you’re making candy or baking bread, cooking steak, or grilling meat, you’re dealing with tiny temperature ranges, where you have to get the temperature just right. That’s where thermometers come in. They become vital if you don’t just want to guess based on touch, but want an exact, precise reading. More often than not, you’ll find recipes directing you to preheat oil to a very specific temperature or to fry your onions to perfection by pulling them from the heat at the right moment.

More to the point, in addition to making you a better cook, thermometers safeguard you against foodborne diseases. You can dramatically shrink your chances of contracting such an illness if you monitor the temperature and wait until that chicken breast is safe enough to serve. The alternative to that method would be overcooking your food, which drains the flavor of the food and also leaches off essential nutrients. That degrades the quality of your diet, but it also makes it harder to digest it.

But not all thermometers are created equal. We’ve had them for centuries, and over their history, they’ve become more and more sophisticated. For culinary purposes, you want precision, accuracy, quick response, and above all, safety. Digital thermometers, or more accurately, infrared thermometers promise all these features. You just have to point them at the surface and pull the trigger. They allow you to take temperatures from a distance (good for safety), and they display the results instantaneously.

In the paragraphs that follow, we’ll look at the working of an infrared thermometer, how to choose the right infrared thermometer for your kitchen, and factors that need your consideration before you hit that ‘Add to Cart’ button. We’ll wrap up with a rundown of some of the best infrared thermometers you can find in the market. Let’s dive in.

How do these thermometers work?

Infrared thermometers belong to a class of thermometers called non-contact thermometers. In simpler terms, they’re ideal for measuring the temperature of a surface from afar – a feature that makes them safer and more hygienic. They operate on a simple principle: all objects radiate infrared light. Cold objects don’t give out as much infrared light as hot objects do.

In layman’s terms, infrared light or radiation is what we call heat. And the thermometer senses how much of this radiation an object or surface is giving off. It does that uses two components: a lens and a detector (also called a thermophile). The lens converges the infrared light from the sources onto the thermophile, which then gets hotter. As it gets warmer, it converts the heat into electrical signals for the device to compute and display as temperature.

How best to use one?

But, of course, this whole process happens in a fraction of a second. You just have to point the laser, pull the trigger, and check the readout. When compared to a more traditional thermometer, you don’t have to come in contact with the hot surface. IR thermometers can also detect an incredibly wide range of temperatures. You can read temperatures as high as 1500 and as low as -200 degrees. But for culinary purposes, you’ll only need to deal with temperatures between 0 to 500.

More to the point, you’ll need to keep in mind the distance-to-target ratio of your thermometer. This ratio is a guide to how large (or small) an area the thermometer will measure. If you are 6 feet away from the source and you’re reading a 1-inch circle, your thermometer has a ratio of 6 to 1 built into it. You can use it to read the temperature on soups, drinks, sauces, and so on. Note that an IR thermometer can only measure surface temperatures, so if you want core temperature, you might want to invest in a contact probe thermometer. At any rate, you can still use your IR gun to monitor the temperatures to ensure that you don’t overcook your food.

Like any traditional thermometer, an infrared gun also requires occasional calibration. You can check the accuracy of your thermometer with the help of ice water since it should always be close to 0 degrees.

Here’s what you need to factor in

First things first, emissivity. What does that mean? Remember how surfaces radiate IR light? While that is undoubtedly true, not all surfaces have the same capacity to radiate. As a rule of thumb, dark surfaces radiate better than reflective surfaces, which is why they have a higher emissivity. So before you shortlist IR guns, take into account their emissivity settings. Some models ship with a fixed setting that usually works for dark surfaces but not so well when it comes to shiny reflective ones. Say, polished stainless steel.

Secondly, the accuracy of most models should suffice unless you are buying for a commercial kitchen. On average, these devices have an error margin of 2.0 percent. But keep in mind that this error margin is strictly dependent on the aforementioned distance-to-spot ratio and how adjustable the emissivity settings are.

What can an IR thermometer be used for?

As touched on above, IR thermometers won’t give you a good measure of the internal temperature of your food, since their operation is limited to surfaces only. So if you want to know when your meat is done, a probe thermometer would still be a better bet. But if you’re going to read the oil temperature, a skillet, a pan, or perhaps your grill, an IR gun would give you a safer, more accurate reading.
