HS-6620 hydrogen leak detector

The HS-6620 portable hydrogen dew point analyzer is compact and easy to operate. Using the dew point transmitter from Finnish company Vaisala, it can accurately measure trace amounts of moisture in the measured gas. The program has a built-in moisture conversion table that directly displays the moisture content, making it intuitive and clear. The sensor is equipped with automatic calibration software that can calibrate dry point drift.

Main Features

Wide measurement range and fast response speed

Zero point calibration upon startup, with user self calibration capability

The verification cycle is long, usually every two years
