Cell Voltage Monitor CVM24P

Stackable cell voltage monitoring (CVM) system designed for H2 fuel-cell stack research, testing and applications. CVM system can be used to prevent damage to individual cells, to monitor lifetime conditions, and to ensure optimal working conditions in applications. CVM24P module is ideal for testing and research purposes.

CVM24P module is designed as a precise automotive-ready solution with additional CAN bus for use mainly in hydrogen fuel cells and electrolyzers research, testing and applications.

For cost-effective solution for application see CVM32A module and kits. For general temperature and voltage monitoring see TEVOMET.
