Abstract
In order to measure the temperature, the instrument is aimed at the object to be measured, the temperature data is read out on the LCD of the instrument according to the trigger, and the ratio of the distance to the spot size and the field of view are arranged. Small make up to remind:
Problems that should be paid attention to when using infrared thermometer:
1, only measure the surface temperature, infrared thermometer can not measure the internal temperature.
2, the wavelength of more than 5um can not be measured through the quartz glass, glass has a very special reflection and transmission characteristics, does not allow infrared temperature readings. But through the infrared window temperature measurement. Infrared thermometers are not used for the temperature measurement of 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 the temperature measurement.
5. Ambient temperature. If the thermometer is suddenly exposed to an ambient temperature difference of 20°C or higher, allow the instrument to adjust to the new ambient temperature within 20 minutes.
Through the introduction of the above content, I believe we have some understanding of it, want to learn more about the relevant knowledge of infrared thermometer, can continue to pay attention to us.
