Low-temperature 1-color Pyrometer

This classification includes one color infrared pyrometers measuring range is 250℃-2200℃. The one color pyrometers currently on market are mostly narrow-band pyrometers. Its principle of temperature measurement is to determine the temperature by detecting the radiant energy that occurs in a narrow wavelength range of an object. The temperature a pyrometer measured is the average temperature in an area, and the measuring result is affected by emissivity, lens contamination and background radiation.

To use 1-color pyrometer mode, the measured area of the object should be large (it can fully fill the target field of view) , object surface should be relatively flat (not curved), measurement direction should less than 30 degrees, and the physical and chemical state of the measured object surface should be stable (not in the process of oxidation, gasification or liquefaction) , the optical channel should with less dust and without blocking and attenuation.

Main applications include: inductioin heating,heat treatment,Galvanized wire ,also suitable for temperature measurement in a good environment. Products in this catalog are usually applied to metallurgical industry(rod and wire mills.Hot rolling mills), foundry, cement kiln, induction heating, heat treatment, heating furnace, vacuum furnace, monocrystalline silicon, polysilicon, semiconductor and other industrial temperature measurement.

1-color pyrometer, monochromatic infrared pyrometer, one color pyrometer, one-color infrared pyrometer
