Toxic Gas Sensor
for industry gas monitoring
Application:
For detecting PH3 in industry, mine or environmental protection fieldProduct characteristics:
Low power consumptionDescription
MQ-E3-PH3 is the sensor of fixed potential electrolysis type. By redox reaction, PH3 and O₂release charge and form the current. The value of current is proportional to the concentration of PH3 and follow the Faraday’s Law. By testing the value of current, the concentration of PH3 is known.
Application
Widely used in industry, mine or environmental protection field for detecting PH3.
