Traditional thermometers are great for taking temperatures of children and are still being used at schools and hospitals all over the country, but there’s a new device that is quickly making them obsolete. Infrared thermometers are the new evolution in temperature taking because they allow a patent’s temperature to be measured without the need for contact. 

This makes them great for the current conditions of the Covid-19 pandemic, which is why businesses are widely adopting them at entry points. An infrared thermometer can take the temperature of any surface and reports quickly and accurately. Here’s the science and concept behind infrared thermometers.

The Concept of Infrared

The technology inside and throughout infrared thermometers is complex, but the concept which makes them work is simple and easy to understand. Every object with mass emits energy, and this energy is emitted in the form of heat. Infrared thermometers read the heat emanating off of objects through a series of sensors, accurately reading how hot the object is both on the surface and on the inside. 

The actual temperature of the object is read by using the difference between the IR rays which emanate from the object and the surrounding environment. The light is funnelled into a detector which converts it to heat and electricity. This process takes only seconds and does not require contact between the thermometer and the object it is measuring.

Benefits of Infrared Technology

Infrared technology has been adopted by many businesses and other institutions at a blistering rate for a few different reasons. First, the accuracy of an infrared thermometer is actually improved from traditional thermometers, which rely on a number of factors to be correct. These advanced thermometers are also safer, as they’re used to measure the temperatures of patrons and students who are potentially sick. 

The lack of contact makes it possible to reuse the thermometer for a number of different people, rather than running through a supply of thermometers or relying solely on disinfection. Finally, these thermometers are simply more durable than their traditional counterparts. They’re tough enough to withstand accidents on a regular basis.

Choosing Your Thermometer

If you’re planning on purchasing an infrared thermometer, it’s important to keep in mind that there are several types, all graded at different temperature ranges. Each of these tools will have a rating that tells you what it’s made to measure and how hot or cold something must be before it cannot properly be read by the individual thermometer you’re buying. To select a thermometer that works best for you, should know what you’re planning to measure. For example, if you’re planning to measure heats as high as 626F, you’ll need a thermometer that is capable of measuring that high. Nearly every infrared thermometer on the market today will measure moderate ranges, but anything higher or lower will need to check out carefully.

Keeping Your Distance

Finally, the last feature you’ll want to look at when buying your infrared thermometer is the distance you’ll be measuring from. There are a few different ratios of distances required to measure the temperature of an object, such as 4:1, 8:1, or even 30:1. These are the most common ratios, but if you need even larger ratios, you’ll have to conduct a thorough and careful search for such a thermometer. The larger the ratio, the further away you can be from your object and still draw an accurate and quick reading. You should try to find a thermometer with a ratio that most closely matches the distance you’ll be standing when you measure your objects. If you know you’re going to be close to the object being measured, you probably won’t want a ratio of 30:1. On the other hand, if you need an abundance of space, you’ll want a ratio far larger than 4:1.
