Configuration review

Decide Whether a Simple Rack Is Enough

Start with the application, required measurements and operating boundary. A model label alone does not establish which modules, interfaces or records are included.

Test objective

List the experiments and measurements needed; a simple rack is not a substitute for a fully instrumented test platform.

DUT interface

Confirm active area, cell or stack fixture, fittings and available assembly drawing.

Operating range

State current, voltage, water and temperature needs within the intended teaching or basic-test duty.

Release scope

Confirm the supplied instruments, safety functions, instructions and functional checks.

Basic PEM Electrolyzer Test & Teaching Activities

IV Curve Scanning

Map the voltage-current relationship of your PEM electrolyzer to understand basic performance characteristics.

CC/CV Stability Testing

Evaluate long-term durability and efficiency trends under constant current or constant voltage modes.

Water & Temperature Observation

Monitor deionized water input and operating temperatures (up to 60°C) during active electrolysis.

Operating Data Review

Log and export essential I-t and IV data points directly via USB for post-test analysis and lab reports.

Inside HELE

Inside Our Manufacturing & Quality System

For a simple rack, useful release checks include the approved electrical connections, water circuit, instrument indication, accessible shutoff functions and a documented functional run. The exact verification scope should match the supplied configuration and training purpose.

Approved configuration

Check the module list, connections and instruments against the order drawing.

Functional evidence

Define the test conditions, records and documents required for release.

FAQ

What current and voltage range does the rack support?

The system supports 0–15V voltage range and 0–30A current range.

What tests can it perform?

The system supports IV curve scanning, manual voltage adjustment, current recording, and long-duration stability testing under CC or CV mode.

Does it include water treatment?

The system uses deionized water, with a conductivity requirement below 1.5 μS/cm. The water flow rate is 300 mL/min.

Can test data be exported?

Yes. The system supports exporting IV and I-t testing data through USB.

Can I install my own electrolyzer?

Yes. The system mainly supports PEM electrolyzers and allows quick installation and replacement of custom electrolyzers according to fixture compatibility.

When should I choose the larger Test Platform?

If you require higher currents (up to 60A), higher temperatures (up to 80°C), pressurized testing, adjustable water flow, or advanced gas analysis, the Single-Channel Test Platform is the required upgrade.
