  • Principle Introduction
Principle Introduction:
Winsen Electronics, as a professional gas sensor manufacturer, produce hydrogen sensor, industrial H2 sensor, using fuel cell/ electrochemical working principle.
ME4-H2 hydrogen sulfide gas sensor is constant potential electrolysis type. Oxidation-reduction reaction with hydrogen 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. So the concentration of the target gas could be got by measuring the value of current.
Applications :
It is used for hydrogen detection in industrial occasion and environmental protection field.
Technical parameters :

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