NDIR Methane Sensor SJH Series

Cubic Sensor and Instrument Co.,Ltd. has developed diverse mature technology platforms of non-dispersive infrared (NDIR) for methane emissions detection in oil and gas industry

NDIR technology relies on the principle that specific gases absorb infrared light at characteristic wavelengths. Based on NDIR technology, Cubic innovatively developed the miniature low power NDIR gas sensor, SJH-5B-SL NDIR non dispersive infrared sensor, which can detect 0 to 5% Vol methane (CH4) concentration. With the low power consumption design, it can be applied for the scenarios that require optimal energy efficiency, battery-powered portable or wearable detectors. SJH-5B-SL could enable continuous working current as low as 1mA, and achieve micro ampere level further through flexible intermittent working model. Besides, it continuously maintains excellent performance for superior accuracy over full temperature range and long-term stability based on matrix calibration mechanism and dual beam design.

In drilling, pipeline, and oil and gas storage facilities, Cubic NDIR CH4 sensor SJH-5B-SL provides real-time data, enabling rapid response to methane leaks to realize precise and reliable industrial safety alarm.

Due to the advantages of diverse mature technology platforms, Cubic provides innovative solutions to methane emissions, which will be favorable for methane emissions monitoring in oil and gas industry with the deployment across both upstream and downstream. At the same time, facing the challenges of environmental emissions, safety monitoring, and production optimization in oil and gas industry, Cubic will insist on technological innovation, continue to cultivate in the field, and consistently deliver qualified and reliable gas sensing solutions.
