How to use the infrared thermometer correctly?
Now handheld infrared thermometers should be quite extensive, but how to use infrared thermometers correctly, the following is an introduction:
When the handheld infrared thermometer measures the temperature of the object to be measured, the infrared thermometer should be aimed at the object to be measured, and the ratio of the measurement distance to the spot size should meet the requirements of the field of view, neither too close nor too far. Then press the trigger button to read the measured temperature data on the LCD display of the instrument. There are five important things to remember when using an infrared thermometer.
1 Ambient temperature. If the infrared 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.
2. Only measure the surface temperature of the object. Infrared thermometers cannot measure the internal temperature of objects.
3. Pay attention to the environmental conditions. Steam, dust, smoke, etc. will block the optical system of the instrument and affect accurate temperature measurement.
4. Locate hot spots. To find a hot spot, first aim at the target with the instrument, and then scan up and down on the target until the hot spot is determined.
5. Handheld infrared thermometers cannot measure temperature through glass. Glass has very special reflection and transmission characteristics, and it is not possible to take accurate temperature readings, but it can be measured through the infrared window. Infrared thermometers should preferably not be used to measure the temperature of shiny or polished metal surfaces (stainless steel, aluminum, etc.).
