1. Product Title

Crowcon Xgard4 CH4‑ Flameproof Fixed Methane (CH4) Flammable Gas Detector

2. Product Overview

Xgard4 CH4 is a flameproof fixed flammable‑gas detector from Crowcon Xgard Type 4 series, engineered for methane (CH4) detection in high‑temperature hazardous‑area environments. Equipped with poison‑resistant pellistor sensor, it measures methane concentration from 0‑100 %LEL, delivering mV‑bridge analog output signal to gas‑monitoring control panels and DCS systems. ATEX flameproof enclosure permits installation within Zone 1 / Zone 2 hazardous locations. The unit provides continuous flammable‑gas hazard monitoring for refineries, gas plants and offshore facilities.
