EmailThe APH-500 generates hydrogen by electrolysis. It uses potassium hydroxide aqueous solution as electrolyte, precious metal as electrode, adopts the latest membrane separation technology to separate hydrogen and oxygen completely, and adopts the transition group metal catalytic technology in the electrolytic cell, so that the hydrogen oxygen content of the hydrogen production is less than 3 nmol/mol. The program control of this instrument adopts high sensitivity, fuzzy control automatic tracking system, eliminates the pressure regulator valve, realizes automatic constant pressure, constant flow, and makes the pressure stabilization accuracy range less than 0.001MPa. It can realize fully automatic adjustment (0-500ml/min) according to the amount of hydrogen required by the chromatograph. When the user stops using the gas, the instrument automatically stops hydrogen production to avoid overpressure in the system, ensuring safety.
Internal single-chip computer intelligent control with a Chinese LCD screen for easy status check;
Built-in water pump with intelligent automatic replenishment; fully automatic adjustment of hydrogen flow with constant pressure and flow rate;
Membrane separation technology and effective dehumidification device are adopted to reduce the original humidity;
Internal liquid storage barrel and filter all made of stainless steel, more suitable for harsh environments;.
Safety devices with automatic anti-return alkali overpressure automatic protection;
Auto shutdown for hydrogen leakage (over flow) with buzzer alarm tone; Adjustable upper limit of hydrogen leakage flow and leakage time according to demand (By default, hydrogen production will be stopped if the hydrogen flow is greater than 480ml/min for 30 minutes.).
