The ValveBox is used to switch between different measuring gas points (16-fold or 6-fold) and provides a continuous, heated flow of measuring or calibration gas. The main applications are the purity measurement of hydrogen for PEM fuel cells, as well as the testing of fuel cells. Depending on the application, the measurement is performed using HydrogenSense or ComboSense.
The measurements are completely software controlled via manual operation or automated via AK interface.
