Advantages of double-color infrared thermometer
1. Advantages of using two-color thermometer in polysilicon production
(1) The principle of double colorimetric temperature measurement is used to directly measure the real temperature of the target, and it is basically not affected by the emissivity of the material, and no emissivity compensation is required.
(2) With visual aiming, the target can be seen directly.
(2) Not sensitive to slight contamination of the window.
(3) Get rid of the dependence on the absolute energy of infrared, and insensitive to signal attenuation.
2. Advantages of using double-color thermometer in vacuum sintering furnace:
(1) Temperature measurement is not affected by optical path pollution.
(2) Not sensitive to window pollution.
3. The advantages of using a two-color thermometer in a salt bath furnace:
(1) Temperature measurement is not affected by smoke pollution.
(2) Slight contamination of the thermometer lens does not affect the temperature measurement.
4. The advantages of using a two-color thermometer for hot rolling of steel billet and steel strip:
(1) There is no emissivity effect due to scale.
(2) The lens of the two-color infrared thermometer is slightly polluted, which does not affect the temperature measurement.
