How to measure temperature with infrared thermometer?
In order for the infrared thermometer to accurately measure temperature, aim the infrared thermometer at the object to be measured, press the trigger to read the temperature data on the LCD of the instrument, and ensure that the ratio of distance to spot size, and field of view are arranged. There are a few important things to remember when using an infrared thermometer:
1. It only measures the surface temperature, and the infrared thermometer cannot measure the internal temperature.
2. Temperature measurement cannot be carried out through glass. Glass has very special reflection and transmission characteristics, and infrared temperature readings are not allowed. But the temperature can be measured through the infrared window. It is best not to use infrared thermometers for temperature measurement on bright or polished metal surfaces (stainless steel, aluminum, etc.).
3. Locate hot spots. To find hot spots, the instrument aims at the target, and then scans up and down on the target until the hot spots are determined.
4. Pay attention to environmental conditions: steam, dust, smoke, etc. It blocks the optical system of the instrument and affects temperature measurement.
5. Ambient temperature. If the infrared thermometer is suddenly exposed to an ambient temperature difference of 20 degrees or higher, allow the instrument to adjust to the new ambient temperature within 20 minutes.
Why use a non-contact infrared thermometer?
The non-contact infrared thermometer uses infrared technology. It can quickly and conveniently measure the surface temperature of an object; it does not require mechanical contact with the measured object to quickly measure the temperature reading. Just aim, press the trigger and read the temperature data on the LCD display. Infrared thermometers are lightweight, small and easy to use, and can reliably and accurately measure hot, dangerous or hard-to-reach objects without contaminating or damaging the objects being measured. Infrared thermometers can take several readings per second, while contact thermometers take several minutes per second.
How does an infrared thermometer work?
Infrared thermometers receive invisible infrared energy emitted by a variety of objects themselves. Infrared radiation is 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. Infrared wavelengths are commonly expressed in microns, and the wavelength range is 0.7 microns-1000 microns. In fact, the 0.7 microns-14 micron band is used in infrared thermometers.
