Precautions for using portable thermometer
When using a portable thermometer to measure the temperature of a target, the infrared radiation of the target within its band range must first be measured, and then the temperature of the measured target is calculated by the thermometer. A single-color thermometer is proportional to the amount of radiation within the band; a two-color thermometer is proportional to the ratio of the amount of radiation in the two bands.
What should you pay attention to when using a portable thermometer:
To locate the hot spot, to find the hot spot, the instrument aims at the target, and then scans up and down on the target until the hot spot is determined.
Temperature measurement cannot be carried out through glass. Glass has very special reflection and transmission characteristics, which does not allow accurate infrared temperature readings. But the temperature can be measured through the infrared window. The portable thermometer is not intended for temperature measurement on bright or polished metal surfaces (stainless steel, aluminum, etc.).
Only the surface temperature is measured, the portable thermometer cannot measure the internal temperature.
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 portable 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.
1. To avoid damaging the portable thermometer, please first use compressed air to remove large particles and dust, and then wipe it with a piece of cloth.
2. Gently wipe the lens with a slightly dampened non-corrosive solution or a mild diluted soap solution (do not use a soft cotton cloth immersed in the liquid) that is labeled for cleaning the lens. ) Wipe the lens with a soft cotton cloth (do not immerse the cloth in liquid). Use a clean computer monitor cleaning cloth to gently wipe the display.
3. Use a clean computer monitor cleaning cloth to gently wipe the display screen.
4. Use a clean and slightly damp cloth to gently wipe the thermometer body. If necessary, dampen the cloth with a solution of water and a small amount of mild soap.
5. After using the portable thermometer, please put the lens cover on the portable thermometer as soon as possible and put it in the carrying case for storage.
