Infrared Thermometer: How to Use

An infrared thermometer has many uses. It is an invaluable tool in the kitchen for measuring food and cooking surfaces without any contact. Its ability to measure temperature remotely is also valuable in other industries, making it a practical investment. This handy guide on using an infrared thermometer is for you if you are new to this product.

How Do Infrared Thermometers Work?

An infrared thermometer is a handheld device, also known as a thermometer gun, that captures infrared radiation emitted by objects or surfaces. The gun processes this information and converts it into temperature readings displayed on the screen.

Infrared thermometers work using the concept of thermal radiation. This principle eliminates the need for physical contact when using thermometers to read temperature. It also enables you to take temperature measurements from a distance while maintaining the accuracy of the reading.

The point-and-click concept of using infrared thermometers makes them easy to use and highly convenient. A thermopile projects infrared light onto an object. The light measures the difference between the infrared light emitted by an object and the light in its immediate environment.

An infrared thermometer also converts the radiation reading into heat. That heat is converted into an electrical signal, which powers the thermometer display.

While infrared thermometers differ, they work the same way as described above.

Infrared Thermometer: How to Use

Anyone new to using an infrared thermometer might find it intimidating, since its design and function differ from those of traditional thermometers. However, it is easy and convenient.

Step 1: Turn the thermometer on.

Switch the infrared thermometer on using its power button.

Step 2: Pick your preferred setting.

Some infrared thermometers allow you to choose measurement settings. For example, you can choose to read it in Celsius instead of Fahrenheit (or vice versa).

Step 3: Aim the thermometer gun.

To measure the temperature of an object or surface, hold the thermometer gun approximately six inches from the target. Hold the device still until the temperature reading is shown on the screen.

Step 4: Keep it steady.

Keep the infrared thermometer steady while you hold the trigger. Keeping it still improves the reading’s accuracy by preventing the sensor from confusing which area you are measuring.

With these easy steps, you’ll have your temperature reading in a few seconds.

When to Use Infrared Thermometers?

An infrared thermometer is invaluable for taking temperature readings from a distance. However, it is not the best tool for all temperature checks, so you must know when to use it.

The most important thing to keep in mind is that infrared thermometers can measure surface temperature. Therefore, it is not suitable for taking the internal temperature of food.

Knowing the limitations of an infrared thermometer, here are the most common uses for this type of thermometer:

Use it to spot-check the temperature of liquids and semi-solid foods.
Use it to check the surface temperature of pots, pans, and cookware.
Use it to measure the temperature of the oven, grill, or other cooking appliances.
Use it to test the insulation of certain surfaces.
Use it for contactless temperature readings.

Is It Safe to Use Infrared Thermometers on Humans?

Yes. Infrared thermometers can be used on humans. Make sure that the thermometer model is FDA-approved before you use it, though. This will ensure the thermometer is safe to use and provides accurate readings.

Infrared thermometers are the best way to measure someone’s temperature without contact. In addition, they provide quick readings in just a few seconds.

What is the Temperature Range of Infrared Thermometers?

Infrared thermometers have applications in the kitchen and across various industries. While this type of thermometer is advantageous for handling high-heat surfaces in the kitchen, it can also withstand intense heat in other industrial applications.

The actual temperature range that infrared thermometers can measure will vary from model to model. Most infrared thermometers can measure temperatures from 100 °F (38 °C) to 10,000 °F (5,538 °C).

Before using an infrared thermometer for a specific application, check the maximum temperature range. Exposing the temperature to a higher level of heat than it is designed for can cause damage.

Advantages of Infrared Thermometers

You can enjoy several benefits when using infrared thermometers, whether in the kitchen or in industrial applications.

Infrared thermometers can measure objects at a distance. There is no need to come into contact with the object or surface.
It can produce quick readings in just seconds.
It features a compact, lightweight design.
It is easy to use and read the temperature even if it’s your first time using the device.
It reduces the risk of cross-contamination during food preparation or cooking.
It is easy to clean and maintain.
It is highly versatile, as you can use it across various industries and applications, not just for cooking.

It’s important to remember that the above benefits result from using the infrared thermometer correctly. Note the best practices for using this tool to ensure accurate readings. For example, you need the infrared thermometer to adjust to the ambient temperature of the environment. If you use it in a walk-in freezer, give it time to adjust to the temperature before taking temperature readings.

You must also account for emissivity when measuring the temperature of food or an object. The higher an object’s emissivity, the higher its temperature reading on an infrared thermometer. The more you understand how emissivity works, the more you can understand how it impacts the quality of your reading. You must assess the material you are reading before you use an infrared thermometer. It ensures that the material does not interfere with the reading nor inaccurately report the temperature.

No matter in what industry you use an infrared thermometer, it’s clear that this tool increases efficiency and reliability. Always remember the correct way to use it to ensure the most accurate results every time.
