How It Works
The hydrogen generator operates through controlled electrochemical processes to produce high-purity hydrogen gas from water. The system employs water electrolysis to generate hydrogen on demand, eliminating the storage and handling requirements of pressurized gas cylinders.
Internal purification systems remove trace impurities and moisture from the generated hydrogen stream, ensuring gas purity suitable for sensitive analytical applications. Pressure regulation and flow control systems maintain consistent delivery conditions, while safety features monitor system parameters and provide automatic shutdown capabilities if operating conditions exceed safe limits.

A: The hydrogen generator produces hydrogen without preheating, enabling rapid startup and immediate use.
Q: Is the noise level important for my laboratory?
A: Both models are rated at ≤65 dB working noise.
Q: Can I adjust the hydrogen flow rate?
A: The 300 mL/min model offers adjustable flow from 0–300 mL/min. The 600 mL/min model delivers a rated output of 600 mL/min.
Q: What safety features are included?
A: Features include water-shortage shutdown, overpressure shutdown, safety-valve protection, and fault-status indication for safe laboratory operation.
How It Works
The generator makes hydrogen by electrolyzing water. It is built from a water tank, an electrolyzer, a power supply, a gas-water separator, a drying pipe and a pressure controller. After power-on the unit waits in standby; the start/stop button on the panel starts and stops hydrogen production.
The pressure controller holds the outlet at a constant pressure, adjustable from 0 to 0.4 MPa, while the display shows the flow and indicates any fault. The unit shuts down on water shortage or over-pressure. Only pure water is added during operation, and electrolysis produces only hydrogen and oxygen.
