What are the uses of infrared thermometers?
Non contact infrared thermometers use infrared technology to quickly and conveniently measure the surface temperature of objects. Quickly measure temperature readings without the need for mechanical contact with the object being measured. Just aim, press the trigger, and read the temperature data on the LCD screen. Infrared thermometers are lightweight, small in size, easy to use, and can reliably measure hot, dangerous, or difficult to reach objects without contaminating or damaging the object being measured. Infrared thermometers can measure several readings per second, while contact thermometers require several minutes to measure per second.
Infrared thermometers receive invisible infrared energy emitted by various objects themselves. Infrared radiation is a part of the electromagnetic spectrum, which includes radio waves, microwaves, visible light, ultraviolet, R rays, and X-rays. Infrared is located between visible light and radio waves, and its wavelength is commonly expressed in micrometers, ranging from 0.7 micrometers to 1000 micrometers. In fact, the 0.7-14-micron wavelength band is used for infrared thermometers.
In order to measure temperature with an infrared thermometer, align the infrared thermometer with the object to be measured, press the trigger to read the temperature data on the instrument's LCD, and ensure that the distance and spot size ratio, as well as the field of view, are arranged properly. There are several important things to remember when using an infrared thermometer:
1. Only measuring surface temperature, infrared thermometers cannot measure internal temperature.
2. It is not allowed to measure temperature through glass, as glass has special reflection and transmission characteristics, and infrared temperature readings are not allowed. But temperature can be measured through an infrared window. It is best not to use infrared thermometers for temperature measurement on bright or polished metal surfaces (such as stainless steel, aluminum, etc.).
3. To locate hotspots, the instrument aims at the target and then performs up and down scanning movements on the target until the hotspot is determined.
4. Pay attention to environmental conditions such as steam, dust, smoke, etc. It blocks the optical system of the instrument and affects temperature measurement.
5. If the infrared thermometer is suddenly exposed to an ambient temperature difference of 20 degrees or higher, the instrument is allowed to adjust to the new ambient temperature within 20 minutes.
