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