Dew point analyzer

Dew point analyzer

    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.

Dew point analyzer adopts imported capacitive dew point sensor, which has the characteristics of quick response, high sensitivity and good repeatability.

Dew point analyzer main features:

1.With the function of data auto-storing, the interval of recording time can be set 

2.freely among the range of 1min~24h and the alarm point can be set freely, too;

3.It can do one-way or two-way communication with the computer;

4.It has a long calibration cycle, 2 years in usual.
