Cubic CB-HCHO VOC Sensor

CB Series VOC Gas Sensors

Modules for detecting formaldehyde and TVOCs.

Supplier: Cubic Sensor and Instrument Co. Ltd

Technology type: VOC 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.
