MQ136 hydrogen sulfide sensor
MEu-H2S hydrogen sulfide gas sensor is a constant-potential electrolytic sensor. Hydrogen sulfide and oxygen undergo corresponding redox reactions at the working electrode and counter electrode and release charges to form a current. The current is proportional to the concentration of hydrogen sulfide. Can determine the level of hydrogen sulfide concentration.
Sensor Features
Excellent repeatability and stability.
main application
Detection of hydrogen sulfide in industrial sites and environmental protection fields.
Portable hydrogen sulfide detection instrument.
Fixed point hydrogen sulfide detector.
