Instrument Overview:
The ZQHF-300 series high-purity hydrogen generator consists of an electrolytic separation cell, a switching power supply, pressure control, drying and purification, flow display and other systems. The "heart" electrolytic separation cell of this instrument is a barrel structure. Liquid storage, hydrogen production, and oxygen discharge can be carried out simultaneously, and its advantages of large electrolysis area, low cell temperature, good performance, and higher purity make it the best replacement for plate electrolysis cells. This instrument is equipped with a non reflux device, which can effectively ensure that there is no reflux phenomenon in the instrument.

Instrument technical parameters:
1. Power supply voltage: 220V 50Hz
2. Maximum power: 150W; 180Ｗ
3. Environmental temperature: 0-40 ℃ Relative humidity<>
4. Environmental conditions: No large amount of dust or corrosive gases.
5. Gas purity: 99.999% (relative oxygen content)
6. Output flow rate: ZQHF-300 type 0-300 ml/min
ZQHF-500 type 0-500 ml/min
7. Output pressure: 0.4Mpa (if special pressure is required, notify the manufacturer before leaving the factory to determine otherwise)
8. External dimensions; 5U
9. Weight: Approximately 12kg for ZQHF-300 model; approximately 13kg for ZQHF-500 model

Instrument features:
1. Easy to operate, just turn on the power switch to produce gas.
2. When the pressure reaches the set position, the gas production will change according to the amount of gas used, producing as much as needed, and the output pressure is stable. The flow rate is displayed by LED digital display, which is more intuitive and eye-catching.
3. Equipped with automatic water replenishment function, it can be used continuously or intermittently.
4. Integrated liquid storage, electrolytic hydrogen production, and oxygen discharge, with low pool temperature and long lifespan. The purification device and gas storage tank are made of stainless steel material.
5. Equipped with a non reflux device, it can effectively ensure that the instrument has no reflux phenomenon.
