2h-160DV Rotary Piston Vacuum Pump From China Real Manufacturer
This classification includes two color infrared pyrometers measuring range is 250℃-2200℃.
Compared with one color infrared pyroemter, two color pyrometer measuring result will not change with state of object surface (surface roughness or surface chemical state), that means two color infrared thermometer accuracy will not be affacted, while the 1-color pyrometer will.
Products in this classification 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.

The Rotary Piston Vacuum Pump is a versatile device that can operate independently or serve as a backing pump when used with other vacuum pumps such as Roots Vacuum Pumps, Oil Boater Pumps, and Oil Diffusion Pumps. It's important to use appropriate accessories if the gas being pumped is corrosive, reactive with vacuum pump oil, or contains vapor and dust.

3Low-temperature 2-color Ratio Pyrometer
The optical part of pyrometer, such as glass, will accumulate some dust in the surfac after using for a period. Water, gas, oil vapour, dust in the air will reduce the emissivity coefficient, so the monochromatic pyrometer will reduce the measured value at this time. The Dual 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. And user just need to wipe the glass when it is too dirty.
Monochromatic thermometers cannot measure objects smaller than the field of view. When the object does not fill the field of view, the measurement temperature will be low. A bicolor pyrometer can measure objects smaller than the field of view.
