When using an infrared thermometer to measure temperature, point the infrared thermometer at the object to be measured and press the trigger to read the temperature data on the LCD of the instrument to ensure that the distance and spot size ratios are arranged. There are several important things to keep in mind when using an infrared thermometer:
1, only measuring the surface temperature, infrared thermometer can not measure the internal temperature.
2, can not be measured through the glass, the glass has a very special reflection and transmission characteristics, does not allow accurate infrared temperature readings. However, temperature can be measured through the infrared window. Infrared thermometers are best not used for temperature measurement on polished or polished metal surfaces (stainless steel, aluminum, etc.).
3, positioning hotspots, to find hot spots, the instrument aims at the target, and then on the target for scanning up and down movement, until the determination of hot spots.
4, pay attention to environmental conditions: steam, dust, smoke and so on. It blocks the instrument's optical system and affects accurate 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 a new ambient temperature within 20 minutes.
