Detailed description
The MH Multipass 5,2 - 2 channel is a dual-channel, high-precision Herriott-type gas cell engineered to increase sensitivity in non-dispersive infrared (NDIR) gas analysis. The optical path is extended to approximately 5.2 m inside a compact 120 mm housing, enabling simultaneous measurement on two optical channels for multi-component analysis or reference signal acquisition.

The 6061-T6 aluminum housing with a PTFE protective coating provides corrosion resistance and reduces contamination risk in humid or chemically aggressive environments. Gold-coated K9 mirrors and CaF2 windows ensure high reflectivity and infrared transparency across a broad spectral range. Stable mirror mounts and a vibration-resistant mechanical design maintain optical alignment and long-term signal stability under industrial conditions.

The gas-tight O-ring sealing system supports safe operation from 500 to 1300 mbar and temperatures between -20 °C and +60 °C, delivering consistent measurement performance over the device lifetime. The cell is optimized for integration with Micro-Hybrid JSIR 350-4 emitters and dual-channel thermopile or pyroelectric detectors, providing a matched optical interface for All-in-One NDIR platforms.

Its mechanical and optical layout allows configuration for a wide range of gases and monitoring tasks, including emission monitoring systems, analytical instruments, and OEM NDIR modules where compact size and high sensitivity are required.
