Prevalence of infrared thermometer especially digital infrared thermometers, across various sectors is becoming prominent day by day, after the Attack of Covid-19. This device that is available in numerous shapes and sizes and varied features detects temperature from a portion of the thermal radiation emitted by the object being measured. This thermometer, also called laser thermometer does not need to physically touch but only scan the surface of the object whose temperature is being measured. Besides, they take less than a second to read and report the temperatures.

An infrared thermometer functions by using a series of lenses to collect infrared light that is then detected by sensors within the thermometer and measured. The thermometer projects the reading in either Celsius or Fahrenheit or both digitally, depending on the model. Portable infrared thermometer and permanent infrared thermometers are the two types available in the market, among others. A portable device is small, most commonly used in a doctor’s office to read the patient’s temperature. Permanent thermometers are larger, mounted devices that function as infrared cameras and are designed to constantly monitor an area.

As industries strive for more accuracy and sophistication, they are also adapting to changing trends and innovative technology. Infrared thermometers have taken the place of conventional thermometers in a wide range of industries as they offer accuracy and do not require physical contact. This quality of the thermometer is convenient in order to check the high or cooling temperature of materials in the manufacturing sectors like that of plastics, metals and ceramics. These are ideal for cooking and baking sectors as well as for medical purposes. Since the thermometers are no-contact devices, they are particularly useful for measuring and recording the temperature of sick babies. An infrared thermometer comes in handy around the house or a small establishment while fixing appliances, especially those related to heat and electricity.

Today, infrared thermometers are being innovated too meet the various requirements of different applications. These devices have several built-in features that cater to specific sectors. For instance, there are thermometers that can keep a record of several past readings and also device that have digital display with lighting, allowing visibility in dark. There are thermometers that are designed to measure the temperature of objects that are moving, like rollers or moving machinery.

While buying an infrared thermometer, one must consider several factors. One should keep in mind the object that requires measuring and the distance between the thermometer and the object as well as the temperature range required. One must also determine if the thermometer needs to be permanent, fixed, mounted or movable.
