Overview
The Molecular Property Spectrometer (MPS) LEL sensor is an advanced combustible gas detector that uses proprietary sensor technology to internally identify gases and apply appropriate LEL conversion factors. It accurately detects over 14 different combustible gases including hydrogen, butane, ethane, propane, and octane without requiring conversion factors or specific gas calibration. Features include immunity to poisons (H2S, silicone, HCFCs), long sensor life (10+ years expected), annual field response checks only, high humidity operation capability, and CULUS explosion proof approval. Compatible with M2A, S2, and Direct Connect transmitter systems. Includes 2-year warranty on sensor and 1-year on electronics.
