Product Description
Product description
Our methane sensor designed by our company adopts the explosion-proof ExdIMb. It has strong safety, fast response speed and strong anti-interference ability. It has passed our unique compensation algorithm and multi-stage standard gas. Calibration also features long life, high precision, high repeatability and high stability. Applicable to underground pipe corridors, underground parking lots, public toilets, garages, workshops, chemical plants, greenhouse farms, etc. where real-time monitoring of methane concentration is required.
