SRE1008 is a catalytic combustion gas sensor with good stability, reliability and accuracy. It can be used to detect methane gas concentration in different scenarios.
● Gas alarm instrument
● Combustible gas concentration detector
● Fast response time (< 10 sec)
● High linearity (> 99%)
● Low sensitivity to ethanol and acetic acid
● Anti-poisoning by HMDS, H2S, SO2, etc.
● High stability and reliability
