Cell Voltage Monitor CVM-24P

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. CVM-24P module is ideal for testing and research purposes.

CVM-24P 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 applications see CVM-32A or CVM-64H module and kits. For general temperature and voltage monitoring see TEVOMET. For comparison of all models see Overview.
