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 detection system 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 sensor measurements unaffected by other gases
The methane detection system is 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
