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