A handheld infrared thermometer, also known as a portable infrared thermometer, is a compact, portable infrared thermometer.
The infrared thermometer must be calibrated in order for it to correctly display the temperature of the target being measured. If the thermometer used is over temperature during use
In order to measure the temperature, point the instrument at the object to be measured, and read the temperature data on the LCD display of the instrument according to the trigger to ensure that the ratio of distance and spot size and field of view are arranged. There are a few important things to keep in mind when using an infrared thermometer:
Measuring only the surface temperature, the infrared thermometer cannot measure the internal temperature. Temperature cannot be measured through glass, glass has very special reflection and transmission characteristics, and does not allow accurate infrared temperature readings. However, the temperature can be measured through an infrared window. Infrared thermometers are best not used for measuring the temperature of shiny or polished metal surfaces (stainless steel, aluminum, etc.). To locate hotspots, to find hotspots, the instrument aims at the target, and then scans up and down on the target until the hotspot is determined. Pay attention to environmental conditions: steam, dust, smoke, etc. It blocks the optical system of the instrument and affects accurate temperature measurement. Ambient temperature, if the 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.
