Cell voltage monitoring

Solutions for cell voltage monitoring of fuel-cells, batteries and electrolyzers

Solution details

Cell voltage monitoring is crucial in many electrochemical and research applications to prevent damage of individual cells of fuel-cell stack or battery, to monitor lifetime conditions and ensure optimal working conditions. 

Kolibrik.net provides solutions for a wide range of laboratory, industrial, and transport applications.  

Our product portfolio starts with low-cost CVM32A,  32-channel cell-voltage monitor optimized for 1 V cells.

For applications requiring a wider voltage range, higher precision, or more we provide CVM24P, 24-channel cell voltage monitor with measuring range ± 5 V.

Both CVM32A and CVM24P are compact credit-card size modules which can be combined with other modules of the modular KMS system or even customer's rapid development modules such as Raspberry Pi to build complex control and monitoring solutions.

For high-precision and customer configurable applications you can choose TEVOMET - stand-alone device with 16 completely independent channels, each capable of measurement from microvolts up to ±150 V.
