Problems to be Noted When Using Infrared Thermometer
Galvanized Steel Coil products are mainly used in construction, light industry, automobile, agriculture, animal husbandry, fishery and commercial industries. Among them, the construction industry is mainly used to manufacture anti-corrosion industrial and civil building roof panels, roof grilles, etc.; the light industry industry uses it to manufacture household appliance shells, civil chimneys, kitchen utensils, etc., and the automotive industry is mainly used to manufacture corrosion-resistant parts for cars, etc. ; Agriculture, animal husbandry and fishery are mainly used for food storage and transportation, meat and aquatic products freezing processing tools, etc.; Galvanized Steel Coil,Prepainted Galvanized Steel Coil,PPGI,Galvanised Steel Coils,Steel Coils Shandong Rizhaoxin Metal Products Co., Ltd. , https://www.rizhaoxinsteel.com
Infrared temperature measurement technology plays an important role in product quality control and monitoring, on-line fault diagnosis and safety protection, and energy conservation in the production process.
When using infrared thermometers should pay attention to the problem:
1, only measuring the surface temperature, infrared thermometer can not measure the internal temperature.
2. Wavelengths above 5um cannot be measured through quartz glass. The glass has very special reflection and transmission characteristics, which does not allow accurate infrared temperature readings. However, temperature can be measured through the infrared window. Infrared thermometers are best not used for temperature measurement on polished or polished metal surfaces (stainless steel, aluminum, etc.).
3, positioning hotspots, to find hot spots, the instrument aims at the target, and then on the target for scanning up and down movement, until the determination of hot spots.
4, pay attention to environmental conditions: steam, dust, smoke and so on. It blocks the instrument's optical system and affects accurate temperature measurement.
5. Ambient temperature, if the thermometer is suddenly exposed to an ambient temperature difference of 20°C or higher, allow the instrument to adjust to a new ambient temperature within 20 minutes.
