Product Details

Product Description

Product Description
Introduction
CH4 Gas Safety Testing Monitoring Sensor Module is based on NDIR technology that is superior to thermal catalysis and heat conduction technology, and can detect 0 to 100% methane (CH4) concentration. It has the advantages of convenient operation, accurate measurement, reliable operation, simultaneous output of voltage and serial port, and dual beam design. To meet the different requirements of industrial field and laboratory measurement, it is widely used in gas detection and analysis in petrochemical, chemical, coal, medical, laboratory and other fields.

Applications
Fire Alarm
Based on non-dispersive infrared (NDIR) sensing technology, Cubic has developed a miniature infrared carbon dioxide sensor SRH with accurate gas concentration measurement and rapid response time. It has two signal output modes, digital and analog. And it is the best choice in the field of fire alarm.
Underground Pipe Network
Based on non-dispersive infrared (NDIR) sensing technology, Cubic has developed a miniature infrared methane sensor SJH, which can monitor the changes of methane gas concentration online in real time and provide alarm signals to the monitoring system.
The miniature infrared methane sensor SJH has both digital signal and analog signal output modes, and can provide a small size type, which is more flexible in application.
Mine Alarm
Based on the principle of non-dispersive infrared (NDIR), Cubic has developed a miniature infrared methane sensor SJH, which can detect the concentration of methane gas in the air in real time, and promptly alarm when the methane concentration exceeds the safety limit. Cubic miniature infrared carbon dioxide sensor SRH is available in a small size, which is easier to be integrated into any online monitoring system.
Oil And Gas Recovery
Cubic miniature infrared methane sensor SJH and propane sensor SBH, based on non-dispersive infrared (NDIR) sensing technology, can monitor the concentration of methane and propane gas in the exhaust gas after oil and gas recovery in real time, and perform feedback adjustment to improve the efficiency of oil and gas recovery and ensure emissions could fulfil requirements. Cubic miniature infrared carbon dioxide sensor SRH is available in a small size version for more flexible applications.
