Description
Overview
GAOTek dew point analyzer for online measurement of gas water concentration – high accuracy 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.
Features
- The imported capacitive dew point sensor is with a rapid response speed, high accuracy, and good repeatability for features, etc
- With the function of data auto-storing, the interval of recording time can be set
- Freely among the range of 1 min to 24 h and the alarm point can be set freely, too
- It can do one way or two way communication with the computer
- It has a long calibration cycle, 2 years in usual
