2-color pyrometer range 700-3000℃

2-color pyrometer, also known as ratio infrared pyrometer. It uses the ratio of the infrared radiation energy of the two wavelengths in the adjacent channel to determine the temperature. There is a linear relation between the ratio and temperature, the relationship is determined by the performance of the detector. 

These series industrial pyrometer is not only suitable for temperature measurement in general industrial occasions, but also suitable for precise measuring of small targets at long distance, materials with easy changing emissivity, and in occasions with strong attenuation.

In two-color temperature measurement, temperature will not change with the object’s surface state (such different surface roughness or chemical state ), which will not affect the accuracy of temperature measurement, but will have an impact on one-color pyrometer measurement .

The optical part of pyrometer, such as glass, will accumulate some dust after using for a period. The presence of water, gas, oil, etc. in the air will reduce the emissivity coefficient, so the temperature measured by one color pyrometer will decrease. The two-color pyrometer measures the ratio of infrared radiation intensities of two band wavelength in a specific range. With dust, water vapor and other disturbances, the signals of two wavelength fall simultaneously and the ratio remains constant after division. But this does not mean two-color pyrometer does not require maintenance. User still need to wipe the glass when it is too dirty.

STRONG series 2C infrared pyrometer can meet the requirements of two color measuring in various industrial occasions. For example, medium-high temperature below 2000℃, such as: wire rod, hot rolled plate, forging, casting, cement kiln, heat treatment, induction heating, monocrystalline silicon and polycrystalline silicon, etc. It can also be used in ultra-high temperature below 3000℃ measuring, such as vacuum furnace, graphite furnace, high-temperature furnace etc. Measurement has high stability.
