The correct way to use a portable infrared thermometer is as follows
Portable infrared thermometers are quite common nowadays, but how to use them correctly is introduced one by one below:
When measuring the temperature of the object being measured with a portable infrared thermometer, the infrared thermometer should be aligned with the object to be measured, and the ratio of the measurement distance to the spot size should meet the field of view requirements, neither too close nor too far away. Then press the trigger button to read the measured temperature data on the instrument's LCD display screen. There are five important things to remember when using a portable infrared thermometer.
1. Environmental temperature. If the infrared thermometer is suddenly exposed to an ambient temperature difference of 20 ℃ or higher, the instrument is allowed to adjust to the new ambient temperature within 20 minutes.
2. Only measure the surface temperature of the object. Portable infrared thermometer cannot measure the internal temperature of objects
3. Pay attention to environmental conditions. Steam, dust, smoke, etc. can block the optical system of the instrument and affect the accuracy of temperature measurement.
4. Identify hotspots. To detect hotspots, first aim the instrument at the target, and then perform up and down scanning movements on the target until the hotspot is determined.
5. Portable infrared thermometers cannot measure temperature through glass. Glass has very special reflection and transmission characteristics, which cannot be accurately read for temperature, but can be measured through an infrared window. Infrared thermometers are not suitable for measuring temperature on bright or polished metal surfaces (such as stainless steel, aluminum, etc.).
