This classification includes two color infrared pyrometers measuring range start from 600℃. Two-color pyrometer determines the temperature of an object by measuring the ratio of energy at two different wavelengths. The advanced software and hardware design help pyrometers meet the application in harsh environment as moisture, dust, target size change, partial blockage and emissivity change, even if the detection signal attenuates 95%, the temperature measurement results will not be effected.
In two color mode, pyrometer measure the highest temperature in an area without being limited by the size of the measured target. The two-color mode determines the temperature by the ratio of the signal from two wavelength. When with small measuring object, dusty, water vapor and foggy, changing distance, partially occlusion, and frequently changing emissivity, the signals of two wavelength fall simultaneously and the ratio remains the constant after division.
