GE600 mirror dew-point meter, developed on the basis of the principle of cold mirror.
GE600 mirror dew-point meter, developed on the basis of the principle of cold mirror, It’s especially made for measuring gas humidity . Under a constant pressure, the gas with a certain velocity through the closed sensor chamber, by detecting the change of the photoelectric signal, using high precision circuit and advanced algorithms to control the refrigerating unit, the control system will eventually made the mirror surface temperature automatically balance on the sample gas dew point temperature, Then gas dew point temperature can be measured, the detection process of gas humidity has completed.
It Can be widely used in electric power industry, measuring departments, large-scale iron and steel, coal, chemical industry and other fields, it is mainly used for SF6, CO2, N2 and H2 and O2 gas micro water content detection. The maximum permissible error can satisfy the requirements of first level measurement performance for?national metrological verification regulations JJG 499-2004 ?. With advantages for fast measurement speed, high accuracy, small volume, light weight and so on .
