In many applications, standard monochrome thermometers cannot read the correct temperature. These situations include:
1. The target size is small (the size is too small to fill the entire field of view).
2. Dust, smoke or steam obstruct the view.
3. The window becomes dirty and difficult to keep clean.
4. The emissivity of the product changes (alloy or surface condition changes).

The two color pyrometer can work normally even in the presence of these problems and indicate the correct temperature.

What is the difference between two color pyrometer and monochromatic pyrometer? The two color pyrometer is composed of two monochromatic pyrometers, which use two detectors and work at the same wavelength, but the two detectors detect the same high-temperature target.

Since the two color pyrometer directly measures the actual temperature of the target, it is not affected by the emissivity of the material, and there is no need to compensate for the emissivity. Two color pyrometer has a wide range of applications in smelting, casting, steel rolling, forging, powder metallurgy, chemical industry, glass processing, ceramics, medium frequency induction heating, welding and other industries.
