Our Cell Voltage Measurement Box (CVM) enables reliable stack condition monitoring in hydrogen systems with system voltages of up to 1500 VDC. Here, it measures the differential voltage of individual cells (bipolar plates) from electrolysis stacks, fuel cells and battery cells for data analysis. Manufacturer-independent and certified for use in potentially explosive areas, it fulfills all the requirements of the hydrogen industry. The modular connection with HDC quick connector makes the box plug-and-play-ready and is suitable for a rapid ramp-up of the H2 industry.
