CO Sensor
for commercial CO monitoring
Application:
Widely used in commercial especially civil field for CO concentration monitoringProduct characteristics:
Be stable1. Description
MQ-E2-CO-φ20 is the sensor of fuel battery 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.
