9. Matching Sensor Board for High-Resolution Nitrogen Dioxide Sensor (NO2 Sensor) NO2-B43F:
Unique Sensor Board (ISB) Alphasense B4 4-Electrode Gas Sensor - ISB
This unique sensor board (ISB) is used for Alphasense B4 series 4-electrode gas sensors. The regulator provides dual-channel voltage output.
The low-noise bandgap provides bias voltage to NO sensors, while the ISB can measure oxidizing (CO, H2S, SO2, and NO) and reducing (O3 and NO2) gases.
The ISB is configured in four versions for specific sensors: NO, NO2, O3, and CO/H2S/SO2.
