CO Sensor
Application:
Widely suitable for petroleum and petrochemical, metallurgy, mining and other industrial sites and environmental protection areas of carbon monoxideProduct characteristics:
Low power consumption1. Description
MQ-E4-CO is the sensor of fixed potential electrolysis type. By redox reaction, CO and O₂release charge and form the current. The value of current is proportional to the concentration of CO, and follow the Faraday’s Law. By testing the value of current, the concentration of CO is known.
