Like all SMART TESTSOLUTIONS test systems and solutions, our systems for monitoring fuel cells and electrolysers are modular. This allows the construction of customised systems for cell voltage detection and processing. Excellent electrical properties of the modules are a matter of course for us. More than 20 years of CVM experience have gone into the development of the current CVM product family. The products are characterised by high sampling rates, time-synchronous acquisition of a large number of channels, resistance to humidity and problem-free operation under harsh environmental conditions.
