Why is it important to check temperature remotely?
2. Safety. One of the great things about being able to check on temperature remotely is that you don't actually need to touch the object in question. If you are trying to take the temperature of a particularly hot item, you won't need to place your hand, or even another piece of equipment, onto the hot surface.
What is the distance to spot ratio on an IR thermometer?
What does the distance-to-spot ratio mean? It refers to the distance you can be from the object that is being measured while still receiving an accurate reading. So, the bigger the ratio, the farther away you can stand from the target object while still getting a good reading. For example, with a 30:1 ratio you can be standing 30 inches away from your target and still accurately measure an area of 1 square inch. To measure that same area with an 8:1, you would need to be standing 8 inches away. Higher distance-to-spot ratios are usually found on models with very high temperature ranges, allowing you stand a safer distance away from the heat source.

How does a temperature gun work?
A temperature gun—a type of infrared thermometer—works by measuring the amount of infrared radiation emitted by an object. The emitted IR radiation is focused onto a thermopile using a lens; the thermopile then converts thermal energy into electrical energy, and finally, these electrical signals are used to determine the temperature of the body.
How is IR radiation reflected?
Thus, IR radiation emitted by an object or a human is first focused onto the thermopile inside the temperature gun using a converging (convex) lens. Next is a thermopile, an electronic device that converts thermal energy into electrical energy.

How does an infrared thermometer work?
Infrared thermometers employ a lens to focus the infrared light emitting from the object onto a detector known as a thermopile.#N#The thermopile is nothing but thermocouples connected in series or parallel. When the infrared radiation falls on the thermopile surface, it gets absorbed and converts into heat. Voltage output is produced in proportion to the incident infrared energy. The detector uses this output to determine the temperature, which gets displayed on the screen.#N#While this entire process may sound complicated, it takes only a few seconds for the infrared thermometer to record the temperature and display in your desired unit.
What is the purpose of infrared thermometers?
Infrared thermometers utilize the concept of infrared radiation to determine the surface temperature of objects without any physical contact. Let's find out what infrared radiation is to get a better understanding of how IR thermometers work.
What is the speed of movement of an object that is not in absolute zero temperature?
Infrared Radiation. Every object that is not in absolute zero temperature has atoms moving within it. This speed of movement is in direct correlation with its temperature. The higher the temperature, the faster will be the movement of molecules. These moving molecules emit energy in the form of infrared radiation.
How does infrared radiation affect thermopiles?
When the infrared radiation falls on the thermopile surface, it gets absorbed and converts into heat. Voltage output is produced in proportion to the incident infrared energy. The detector uses this output to determine the temperature, which gets displayed on the screen.
What is an IR thermometer?
Infrared (IR) thermometers are useful in measuring temperature across a range of industrial and clinical environments. These non-contact temperature measurement devices function well in circumstances where the object is fragile and dangerous to get near to, or when other kinds of thermometers are not practical.
Can we see infrared radiation?
While we may not be able to see infrared radiation, we can still sense it in the form of heat. The heat that we feel from sunlight, a radiator, or a fire are all examples of infrared radiation. It is this heat that the infrared thermometers detect to measure the temperature of objects.
Do infrared thermometers come with warranty?
Warranty is a must-have feature in thermometers, as they are fragile or may even turn out to be defective. No-lens and Fresnel thermometers are cheaper than Mica lens thermometers, which can be a pretty massive investment. If you are buying any expensive thermometer, get the one that comes with a manufacturer's warranty.#N#Infrared thermometers are essential to use while reading the temperature of a surface that's too dangerous, and almost impossible to reach. With the complex inner workings process, these thermometers give rapid results and are simple to use. However, before picking an IR thermometer, try to figure out the temperature range and your application. Also, make sure to use the device correctly and at the right place to get accurate results.
