HOW THE PRODUCT WORKS
Multi-parameter hydrogen analysis for field inspection and gas replacement
Portable hydrogen quality checks for generators and production stations
The RA601H (II) Hydrogen Comprehensive Analyzer is a portable instrument for checking hydrogen purity, dew-point humidity, and oxygen in hydrogen-related systems. It is designed for inspection and gas replacement work on hydrogen-cooled generator sets and hydrogen production stations, combining several measurements in one 4 kg instrument.
Purity measurement for generator gas mixtures
The micro-thermal conductivity purity channel covers H₂ in air from 90–100%, CO₂ in H₂ from 0–100%, and CO₂ in air from 0–100%, with an uncertainty of ±2% F.S and response time ≤15 seconds. An H₂/air range from 0–100% can be customized. CO₂, N₂, and Ar are listed as optional displacement gases; confirm the selected gas and measurement mode before ordering.
Humidity and oxygen measurements
The resistance-capacitance humidity channel measures dew point from −80 to +20 °C. Its response specification is provided at a gas temperature of 20 °C and varies by direction and step: for −60 to −20 °C, 5 seconds (63%) and 10 seconds (90%); for −20 to −60 °C, 45 seconds (63%) and 10 minutes (90%). The electrochemical oxygen channel measures 0–25% with ±1% F.S uncertainty and response time ≤20 seconds.
Portable operation and data handling
The analyzer supports ambient-pressure measurement and hydrogen-pressure input, with automatic humidity-pressure conversion. A built-in 6000 mAh lithium battery is specified for more than 8 hours of operation. The unit includes data storage and a USB interface for export, self-calibration, startup self-check, status prompts, and a humidity-drying protection device.
For a suitable configuration, share your generator or station type, gas replacement sequence, expected mixture and displacement gas, target measurement channels, hydrogen pressure, and field calibration or data export requirements. This helps determine the right portable hydrogen purity analyzer setup for generator maintenance and gas replacement.
