Instrument Description: This instrument mainly by electrolysis system, pressure control system, purification system and display system. Electrolytic hydrogen using the most advanced membrane separation technology, the pressure feedback control system consists of an infrared optoelectronic devices and switching power supply consisting of hydrogen can occur automatically adjust the amount of output as needed to maintain a stable output flow and pressure. Technical parameters: 1, the output flow: SGH-300 0-300ml/min; SGH-500 0-500ml/min; 2, the output pressure: 0 ~ 0.4Mpa (generally set at the factory to 0.4Mpa) 3, hydrogen purity: > 99.999% 4, Maximum Power: SGH-300 150W SGH-500 180W 5, the working conditions: (1) Power: AC 220 ± 10%; 50Hz (2), the ambient temperature :5-40 ℃ Relative Humidity: <85 % environment without severe dust pollution 6, Dimensions: 390 × 185 × 320 (L × W × H) 7, Weight: 10kg Main features: (1) can be replaced by high pressure hydrogen cylinders, the laboratory instrumentation, and ensure safety. (2), the working process of automatic control, simple operation, easy routine maintenance. (3), hydrogen production digital display for easy observation instruments work status and fault diagnosis. (4), long life, continuous or intermittent use, stable gas production, does not decay. (5), with overvoltage protection device, safe and reliable.
