Infrared Thermometer Temperature Gun calibrator minimizes the technical difficulties caused by ultra-small size, allowing users to carry it to every corner of the industrial site and perform on-site calibration of temperature probes that need to be inspected, repaired and calibrated. It eliminates the trouble of disassembling it and returning it to the laboratory for comparison and calibration, and reinstalling the original system, which can greatly improve work efficiency, save time, improve the availability of equipment and systems, and provide excellent performance for on-site automatic control engineers. Maintenance and verification methods. Electricity: Temperature protection and signal transmission of coal-fired power plants, gas-fired power plants, hydropower stations, nuclear power plants, district heating pipe networks, large power transformers. Metallurgy: aluminum, copper, steel mill plant, etc. Petrochemical: oil production, oil pipelines, petrochemical plants, oil refineries. General industry: air conditioning plant, refrigerator, refrigerator, brewery, pharmaceutical, automobile factory. Temperature component manufacturer: platinum resistance, thermocouple and compensation wire cable, temperature switch, temperature sensor manufacturer. Transportation: Aircraft maintenance at the airport, maintenance of large-scale transportation power systems, and ocean shipping as a measure of in-service maintenance. 1. only measure the surface temperature, infrared thermometer can not measure the internal temperature 2. Infrared thermometers are best not used for temperature measurement (stainless steel, aluminum, etc.) on shiny or polished metal surfaces. 3. Position the hotspot, to find the hot spot, the instrument aims at the target, and then scans the target up and down until the hot spot is determined.
