The RA601H(II) Hydrogen Comprehensive Analyzer is mainly used for measuring hydrogen purity, humidity, oxygen content, and CO₂/O₂ levels during gas replacement in hydrogen-cooled generators and hydrogen production stations. Incorporating MEMS technology, it achieves faster response and higher accuracy while reducing size and weight. Ergonomically designed, it is compact and lightweight with a soft rubber back for comfortable portability. Features include large-capacity data storage, USB interface, self-test alerts for abnormal status, and charging indicators. The soft power switch prevents misoperation.

▎Key Features ：

1.Environmental pressure measurement and hydrogen pressure input for automatic humidity-pressure conversion.

2.Built-in humidity drying protection device with self-calibration.

3.Compact A4-sized design for reduced size and weight.
