600 PEM Water Electrolysis Test System
600 Electrolyzer Test System (ETS), Advanced Test System for Research & Development of PEM Electrolyzers
The 600 ETS is a state-of-the-art, full-featured bench-top instrument for detailed evaluation and characterization of PEM electrolyzers. The 600 ETS includes an integrated Power Supply, Potentiostat, Impedance Analyzer for EIS & HFR, and real-time sensors for Product Flow Rate and Cross-over Monitoring. The 600 ETS is ideal for labs requiring detailed control, diagnostic and analysis of a single electrolzyer cell.
Powerful FlowCell-ETS® software offers full control and monitoring of the test cell. Built-in experiments include constant, scanning or step-stair voltage or current controlled measurements. Easy, hands-free switching between control of the voltage or current by the Potentiostat or Power Supply.
