SO2-B4 Sulfur Dioxide Sensor SO2 Detection Sensor

SO2-B4 Sulfur Dioxide Sensor SO2 Sensor Description
Alphasense Sulfur Dioxide gas sensors operate using proven fuel cell technology.

Sensors are available in the following sizes:
32mm diameter package, the best choice for fixed site applications

The SO2 range provides OEMs with reliable sensors for use in a variety of
applications. Strong signal levels combined with low zero current allows
resolution below 1ppm and an operating range for safety applications up to
2,000ppm. The sensors are designed for use in both fixed site and portable

The SO2 sensors offer our electrolyte leak-free guarantee and reliable long-term
detection performance. The leakproof housing is moulded with a colour coded top
for ease of identification.

Matched Transmitter board for SO2-B4 SO2 Sensor
Individual Sensor Board (ISB) Alphasense B4 4-Electrode Gas Sensors
The Individual Sensor Board (ISB) is designed for use with the Alphasense B4
family of four-electrode gas sensors. This potentiostat provides a dual channel
voltage output.
A low noise bandgap provides the bias voltage for NO sensors and the ISB can
measure both oxidising (CO, H2S, SO2 and NO) and reducing (O3 and NO2) gases.
The ISB is configured for specific sensors: NO, NO2, O3 and CO / H2S / SO2 .
Designed for low power applications, the ISB requires 3.5 to 6.4 stable DC supply
at only 1mA.
