Cell Voltage Monitor CVM-24P

A cell voltage monitoring (CVM) system tailored for research, testing and practical application of H2 fuel cells. The CVM system protects the integrity of individual cells and provides valuable data for predictive maintenance planning and performance optimization.

Adapted for research and testing purposes, the CVM-24P system offers excellent accuracy and is designed primarily for electrolyzers.

These ready-to-use cell voltage monitor sets are easily integrated into specialized applications and allow direct connection to a PC via USB or to a PLC via RS-485 bus.

Explore our precision 2.5 V solutions with the CVM-64H module and sets, or opt for the cost-effective CVM-32A module and sets. For broader temperature and voltage monitoring requirements, consider our TEVOMET solutions.

Contact us for customized CVMs to meet your specific requirement.

For comparison of all series see Overview.
