Wall-mount dew point analyzer
Wall-mount dew point analyzer can be widely applied in the online measurement of water concentration in the industries like petrochemical industry, natural gas, industrial gas industry, semiconductor industry, drying industry, food industry, electronic power industry, machine manufacturing industry, air separation industry, pharmacy, etc.
Wall-mount dew point analyzer adopts imported capacitive dew point sensor, which has the characteristics of quick response, high sensitivity and good repeatability.Wall-mount dew point analyzer. The wall mount mode makes it convenient to operate at scene and easy to maintain.
Wall-mount dew point analyzer main features:
1.With the function of data auto-storing, the interval of recording time can be set freely among the range of 1min~24h and the alarm point can be set freely, too;
2.It can do one-way or two-way communication with the computer;
3.It has a long calibration cycle, 2 years in usual.
4.Reverse blow function (optional) can be expanded to prevent the filter from being polluted for too long to influence the measurement of the oxygen concentration;
5.The imported extraction pump is built in.
