Adopting NDIR (non-dispersive infrared) gas analysis technology, Cubic CJH-5 methane gas detector is mainly applied for methane gas leak detection and provides in-time alarm in industrial areas.
The Cubic Sensor CJH-5 methane gas detector adopts NDIR (non-dispersive infrared) gas analysis technology. It is mainly applied for CH4 methane gas leak detector and provides in-time alarm in areas such as natural gas, coalbed methane, landfill, wastewater treatment, and anaerobic fermentation.
NDIR technology to ensure CH4 measurements unaffected by other gases
Available for an oxygen-free environment
Temperature compensation and automatic zero calibration design
Long lifetime with no sensor poisoning
Explosion-proof rating: ExdICT6 Gb, suitable for gas leak safety alarms in multiple fields
