The chilled mirror hygrometer is a precision instrument developed and produced based on Maxwellon’s proprietary Stirling micro-cooler. It is primarily used for automatically measuring the trace moisture content in gases. It utilizes a high-precision optical dew point method, suitable for the detection of dew point/moisture content in bulk inert gases.

Equipped with a dedicated control system, it can perform continuous measurement, mirror heating for cleaning, automatic saving of measurement results, and querying of historical records.

Over the past few years, through continuous updates and iterations, We has optimized the overall structure of the chilled mirror hygrometer. It adopts a dual optical path solution to compensate for measurement errors caused by changes in ambient temperature, significantly improving measurement accuracy, speed, and interference resistance. Additionally, it has reduced the overall weight and size of the device, enhancing its portability.
