Brief Introduction
It adopts high performance dew point transmitter of Finland Vaisala Company as the core measurement unit of the entire system.It integrates multiple up-to-date research achievement and proprietary technology in measurement of dew point, and it has the function of Td,RH,ppm conversion and software upgrading. It is one of existing dew point measurement instruments with the most advanced technique and the most powerful function.
Main Features
Self-calibrating of zero point and slope at starting up (proprietary technology)
Calibration of dew point with full-scale range by single-point method (proprietary technology)
Sensor drying protection device (proprietary technology)
Operation and control by colorized touch screen
Storage and printing* of measurement data
Intelligent prompting of electricity quantity, automatic calibration for slope of intelligent charging protection (proprietary technology)
Lithium battery offers long standby time
Technical Parameters:
Measurable gas: H2, O2, N2, Ar, air etc.(non-acid,non alkaline,non corrosive gases)
