Principle Introduction:
Winsen Electronics, as a professional gas sensor manufacturer, produce ETO gas sensor, industrial ETO sensor, using fuel cell / electrochemical working principle.
ME4-ETO ethylene oxide gas sensor is constant potential electrolysis type. Oxidation-reduction reaction with ethylene oxide gas take place inside of the sensor. The process releases electric charge and generates current. The current is in direct proportion to the concentration of ethylene oxide gas. So the concentration of the target gas could be got by measuring the value of current.
Applications :
For ETO gas detection in petroleum and petrochemical occasion, medicine and environmental protection field.
