KJH-300 High Purity Hydrogen Gas Generator
Introduction
The KJH-300 is a high purity hydrogen gas generator designed for laboratory and industrial use. It offers an easy-to-use interface and provides stable, high-purity gas output, making it a reliable alternative to traditional high-pressure gas cylinders. This device can be operated individually or simultaneously, and supports both continuous and intermittent operation without compromising gas purity. Its multi-protection system ensures safe and stable performance.
Â
Features
1. Utilizes electrolytic separation to extract hydrogen and oxygen from water, consuming only water and electricity to achieve high hydrogen purity.
2. Equipped with photoelectric pressure control and over-liquid protection, the generator produces gas on demand under low pressure. It features a minimum hydrogen saving valve for safety and stability, along with an efficient temperature control system that allows continuous peak load operation.
3. Includes a prepositive visible drying chamber that is easy to access. A prepositive deflation valve removes pressure from the tube without discharging it, making maintenance and overhaul convenient.
