An infrared thermometer is a thermometer which infers temperature from a segment of the thermal radiation emitted by an object.
The design consists of a lens to focus the infrared thermal radiation on to a detector. This lens transfers the radiant power to an electrical signal that will be displayed in degree Celsius after showing ambient temperature.
This allows the temperature capacity without getting in touch with an object.
It looks like a gun that is capable of measuring the temperature from a distance.
These infrared thermometers measure the human forehead temperature from a distance and it is the best kind of infrared thermometer for the human body.
The human body infrared thermometer is the best selling device on the market right now due to COVID-19.
Airports in most countries use infrared thermometers to measure the human body temperature.
An infrared thermometer is the best for the human body and provides a better result.
Here, a shopkeeper using the infrared thermometer to check if the customer has a fever.
How it Works
The infrared thermometer acts like a laser and will not be visible through glass, liquids, or other clear surfaces.
One of the super features of an infrared thermometer is that it cannot be seen through the light.
Infrared thermometers cannot measure the air temperature because air does not produce infrared and has very low emissivity. This Thermometer measures infrared with a wavelength of between 4 to 14 microns.
An infrared thermometer cannot measure the temperature inside an object.
We cannot get the exact measurement through any glass or polythene. It can only measure the surface temperature.
The sensors in the infrared thermometer focus the infrared energy emitted by an object onto one or more photodetectors.
Infrared thermometers only work when the battery is placed inside the thermometer.
Using these thermometers saves time and can easily calculate the temperature.
Most people get confused between thermal cameras and thermometers. The two devices are different although both use the same thermal technology.
The following are the leading infrared thermometers in the market today:
