ME-2ZL400
ME-2ZL400
The MegaEISâ„¢ ME-2ZL400 is a specialized workstation with a zero-voltage load function from the Kolibrik MegaEIS Product Family, designed to accommodate electrochemical testing at low voltages.
With 2 measuring channels, it is ideal for testing of small to mid-size stacks — capturing real-time insights into cell uniformity, degradation mechanisms, and efficiency under industrial-scale loads. Capable of delivering up to 400 A and a max. internal power dissipation of 4 kW, the ME-2ZL400 ensures high-precision execution of the most demanding testing scenarios across fuel cell applications.
