Information

Best dual wavelength pyrometer uses the ratio of two bands of infrared radiation energy from adjacent channels to determine the temperature.The relationship between ratio and temperature is linear, which is determined by the performance of the detector.

Best dual wavelength pyrometer eliminates the effects of water vapor, dust, change of target size, partial occlusion, change of emissivity, etc. Best dual wavelength pyrometer does not need to correct the dichroism factor when measuring the vast majority of gray materials. Best dual wavelength pyrometer measures the average of the highest temperature in an area.Best dual wavelength pyrometer can overcome the effects of severe water vapor, dust, change of target size, partial occlusion, change of emissivity, etc. Even if the detection signal is attenuated by 95%, it will not have any effect on temperature measurement results.The software and hardware design is suitable for reliable detection of 1 million times the dynamic range of the signal, meeting the user's requirements for the accuracy and resolution of the instrument.

Best dual wavelength pyrometer does not change with the state of the surface (surface roughness or chemical state of the surface) and does not affect the accuracy of temperature measurement, whereas monochrome thermometers do.

The optical part of Best dual wavelength pyrometer, such as glass, leaves some dust after a period of use. Water, gas, oil in the air, etc., all cause the emissivity coefficient to decrease. Therefore, a monochrome thermometer tends to measure a lower temperature at this time.Best dual wavelength pyrometer is a measure of the ratio of objects in a specific two-band range. When dust, water vapor, etc. occurs, the signal in both bands decreases at the same time, and when divided, the ratio remains unchanged.But that doesn't mean you don't need to maintain the two-color thermometer. You still need to wipe the glass when dust, water vapour, etc. are too dirty.

Monochrome thermometers cannot measure objects smaller than the field of view.When the target does not fill the field of view, the temperature of the measurement will be low.Best dual wavelength pyrometer can measure objects smaller than the field of view.
