Product Introduction
A portable analyzer based on catalytic oxidation and flame ionization detection (FID). Automatic switching between two gas paths first measures total hydrocarbons, then converts non-methane hydrocarbons to CO₂ and H₂O to measure methane. The system calculates NMHC from the results. Referenced methods include HJ 1331 and HJ 1012.
FEATURES
Portable and ready in 10 minutes
Backpack or hand-carry operation for one person. A 10-minute warm-up supports rapid tracking of changing process conditions.
Integrated gas system
The catalytic furnace, hydrogen-storage module and air source share one enclosure, without external cylinders in the standard arrangement.
The catalytic furnace, hydrogen-storage module and air source share one enclosure, without external cylinders in the standard arrangement.
Sealed, heated FID with a 50 ppb detection limit. Catalytic oxidation efficiency ≥99.5%.
Reduced interference
A downstream unheated sampling pump reduces moisture and vibration effects and maintenance demands.
Extended field operation
Solid-state hydrogen storage supports all-day work. The built-in hydrocarbon-free air source means hydrogen is the only consumable gas.
Automation and connectivity
Automatic calibration and catalytic-efficiency evaluation. Remote app operation, RS485 vehicle integration and optional DTU cloud storage.
