Compact and lightweight, it replaces high-pressure hydrogen cylinders and eliminates cumbersome cylinder transportation.
Easy to operate with high automation; high-purity hydrogen generates immediately after powering on.
Equipped with overpressure protection and dual alkali-liquid anti-backflow devices to guarantee safe operation and zero liquid reflux.
Built-in automatic constant pressure and constant current modules deliver stable output flow. The automatic tracking system adjusts hydrogen output fully automatically according to actual consumption, maintaining consistent purity for continuous long-term operation.
Integrated functions: automatic water replenishment, water supply fault protection, hydrogen leakage alarm, operating parameter inquiry and cumulative runtime recording.
Built-in custom dehydration unit requires no consumables, features long service life and stable long-hour operation.
Independent oversized liquid storage tank lowers electrolyte operating temperature and extends refilling intervals.
Wide horizontal barrel electrolytic cell adopts imported special precious metal materials to boost electrolysis efficiency, stabilize cell temperature and greatly prolong cell service life.
The entire gas circuit uses electrolytically polished and ultrasonically cleaned stainless steel tubes to upgrade gas quality and stabilize chromatographic baselines.
RS485 communication is available as an optional configuration.
