CB Series VOC Gas Sensors
The CB series consists of modules with an electrochemical cell sensor used mainly to detect formaldehyde. When formaldehyde gas passes through the sensor, the formaldehyde molecules undergo oxidation-reduction reaction. This generates a small current that is proportional to the gas concentration.
Through mathematical algorithms and scientific calibration, it can simultaneously output also TVOC concentration.
