Product Introduction
UK Alphasense Air Quality Sensor VOC SensorVOC-B4 Description:
VOC-B4 can detect both VOC gas and CO gas.
Using VOC-B4 and CO-B4 sensors together allows estimation of VOC concentration without bias.
Alphasense VOC electrochemical sensors VOC-A4 and VOC-B4 are the perfect partners for our amperometric four-electrode air quality sensors. In ambient air quality applications, VOC-A4 and VOC-B4 should be used in combination with one of our A-series (CO-A4) or B-series (CO-B4) carbon monoxide sensors. Although we recommend using these sensors for air quality applications without bias, the bias of VOC-A4 and VOC-B4 can be changed to 0V, 0.1V, 0.2V, or 0.3V, allowing selection for detecting different types of gases.
