Description

Principle Introduction:
Winsen Electronics, as a professional gas sensor manufacturer, produce H2S/ hydrogen sulfide sensor, using fuel cell / electrochemical working principle.
ME4-H2S hydrogen sulfide gas sensor is constant potential electrolysis type. Oxidation-reduction reaction with hydrogen sulfide and oxygen take place respectively on the working electrode and on the counter electrode. The process releases electric charge and generates current. The current is in direct proportion to the concentration of hydrogen sulfide. So the concentration of the target gas could be got by measuring the value of current.

Applications :
It is used for hydrogen sulfide detection in industrial occasions, mine and environmental protection field.

Technical parameters :

Tips:For more parameter information, please refer to the latest manual provided by salesman.
