Correct use of portable infrared thermometer
When the portable infrared thermometer measures the temperature of the object to be measured, the infrared thermometer should be aimed at the object to be measured, and ensure that the ratio of the measurement distance to the spot size meets the field of view requirements, not too close or too far. Then press the trigger button, and the measured temperature data can be read out on the LCD display of the instrument. There are five important things to keep in mind when using a portable 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. Portable 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 hotspots. To find a hot spot, first use the instrument to aim at the target, and then scan up and down on the target until the hot spot is identified.
5. The portable infrared thermometer cannot measure temperature through glass. Glass has very specific reflective and transmissive properties that prevent accurate temperature readings, but can be measured through the infrared window. Infrared thermometers are best not used for temperature measurement on bright or polished metal surfaces (stainless steel, aluminum, etc.).
