Description

CO-B4 Carbon Monoxide Sensor (CO Sensor) 4-Electrode Description
Alphasense Carbon Monoxide gas sensors operate using proven fuel cell technology.
Sensors are available in the following sizes:
A: 20mm diameter, the industry standard size for portable gas detectors
B: 32mm diameter package, the best choice for fixed site applications
C: 20mm diameter with extra height for additional filter material when measuring combustion gases
D: miniature, with proven long-term performance. Sensors for the next generation of portable gas detectors
The Alphasense family of CO sensors have proven themselves in the field with long term stability and reliable operation, well beyond the two-year warranty, using our patented electrode technology. The ‘X’ sensors have low hydrogen sensitivity, as drop-in replacements for the standard ‘F’ sensors.

Matched Transmitter board for CO-B4 CO 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.
