Locating hot spots, to find hot spots, the instrument is aimed at the target, and then make an up and down scanning movement until the hot spot is identified.
Only measure the surface temperature, can not measure the internal temperature. Cannot measure temperature through glass, can not be accurate infrared temperature readings. But you can measure temperature through an infrared window. Infrared thermometers are best, not for temperature measurement of shiny or polished metal surfaces (stainless steel, aluminum, etc.).
Environmental conditions: steam, dust, smoke and so on. Ambient temperature, if the pyrometer is suddenly exposed to ambient temperature difference of 20 ℃ or higher, the instrument is adjusted to the new ambient temperature within 20 minutes.
Extended information
Handheld infrared thermometer by the optical system, photodetector, signal amplifier and signal processing, display output and other components. Handheld infrared thermometer is convenient, accurate, safe, in the medical, equipment troubleshooting is more widely used. Selection of infrared thermometer should focus on performance indicators (such as temperature range, spot size, working wavelength, measurement accuracy, response time, etc.), ease of use, maintenance and calibration performance and price and other factors.
Production of professional handheld non-contact infrared thermometer, easy to use, solid design, high measurement accuracy, wide temperature range and other characteristics. It has a laser aiming, with backlight display, maximum value, minimum value, average value, difference, data retention, high and low temperature alarm, adjustable emissivity and automatic shutdown function.
