1.VOCSensorVOC-A4Introduction

VOC-A4Both can detectVOCGas, and can be detectedCOGas.

simultaneous useVOC-A4andCO-A4sensor can estimateVOCConcentration.

Alphases VOCelectrochemical sensorVOC-A4andVOC-B4It is the perfect partner for our current-type four-electrode air quality sensor. in ambient air quality applications,VOC-A4andVOC-B4should be with ourADepartment (CO-A4)orBDepartment (CO-B4)One of the carbon monoxide sensors is used in combination. Although we recommend using these sensors for air quality applications without bias,VOC-A4andVOC-B4The bias can be changed0V、0.1V、0.2Vor0.3V, thereby allowing the selection of different types of gases to be detected.
