Toxic Gas Sensor
for hydrogen fluoride gas detection of chemical industry
Application:
Extensive suitable for industrial and environmental protection field of hydrogen fluoride detection.Technical specificationProduct characteristics:
Low power consumptionDescription
The MQ-E4-HF hydrogen fluoride sensor is a fixed potential electrolytic sensor, Hydrogen fluoride gas releases a series of REDOX reactions inside the sensor The discharge charge forms a current, the magnitude of which is proportional to the hydrogen fluoride concentration Following Faraday's Law, fluorination is determined by measuring the size of the electric current Hydrogen concentration.
Application
Widely used in industry or environmental protection field for detecting HF.
