Toxic Gas Sensor
Application:
Widely suitable for the detection of ethylene oxide in petroleum, petrochemical, pharmaceutical and environmental protection fields.Product characteristics:
high precisionDescription
MQ-E4-ETO is the sensor of fixed potential electrolysis type. By redox reaction, ETO and O₂release charge and form the current. The value of current is proportional to the concentration of ETO. By testing the value of current, the concentration of ETO is known.
