But how to use infrared thermometer correctly
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. 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 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 hot spots, you must first use the instrument to aim at the target, and then scan up and down on the target until the hot spot is determined.
5. Handheld infrared thermometer cannot measure temperature through glass. Glass has very special reflection and transmission characteristics, which can not make accurate temperature readings, but can measure temperature through infrared window. Infrared thermometers are best not used for the measurement of bright or polished metal surfaces (stainless steel, aluminum, etc.).
