sulfur dioxide gas sensor

Best Sulphur Dioxide (SO2) Gas Detector (Top Pick ...

· A sulphur dioxide gas detector is composed of electronics and an SO2 sensor. The gas sensor converts the detected gas concentration to an electronic signal for analysis by the onboard microprocessor. After receiving the electrical signal, the processor displays the SO2 concentration reading. If the measurement exceeds the pre-set SO2 alarm value, the alarms are triggered.
