This dedicated online hydrogen generator is specially developed for online VOC monitoring equipment.
Easy operation: hydrogen is produced immediately after power-on. Equipped with two-stage overpressure protection for reliable safety performance.
The entire gas circuit adopts electrolytically polished and ultrasonically cleaned stainless steel tubes to improve gas quality and stabilize chromatographic baselines.
Independent oversized liquid storage tank reduces electrolyte operating temperature and extends water refilling intervals.
Unique automatic anti-liquid-backflow structure completely prevents electrolyte reflux inside the unit.
Built-in automatic constant pressure and constant current modules deliver stable output flow. The automatic flow tracker adjusts hydrogen output fully automatically based on actual consumption, maintaining non-declining purity for uninterrupted continuous operation.
Wide horizontal barrel electrolytic cell adopts imported special precious metal electrolytic materials to boost electrolysis efficiency, stabilize cell temperature and greatly extend the service life of the electrolytic cell.
Front-mounted stainless steel drying tubes avoid aging damage and wear risks from disassembly, facilitating easy inspection and removal.
Equipped with a vent valve for quick desiccant replacement; pressure relief can be completed directly via the vent valve without disconnecting the hydrogen outlet.
Integrated functions including hydrogen leakage alarm, automatic water replenishment and water supply fault alarm.
