Function and application scope:
This instrument uses the absolute humidity measurement method - dew point method principle for measurement, and precisely measures the dew point humidity of gases through semiconductor refrigeration, mirror condensation, and photoelectric detection methods.
This instrument meets the technical requirements of humidity transfer standards and can be widely used for humidity measurement of non corrosive and non explosive gases such as air and nitrogen, as well as for measuring environmental temperature and humidity. It can also be used for calibration and testing of humidity measuring instruments, humidity generators, humidity sensors, and environmental test chambers
