CO-BX Carbon Monoxide Sensor

CO Gas Sensor, Electrochemical, B-Series, ppm-level CO monitoring in H2

High-performance CO detection for safety-critical monitoring, combustion analysis and process control.

Alphasense CO-BX sensors provide high-performance carbon monoxide detection for portable and fixed gas monitors across industrial safety, car park monitoring, combustion analysis and air-quality applications.

These B-Series sized CO sensor come standard with filters to remove hydrogen gas and hence provide low hydrogen cross-sensitivity for combustion and industrial safety applications where CO must be measured in the presence of H2. These CO-BX sensors are recommended for fixed and portable systems, and also have reduced cross sensitivity to H2S / NO2 / NO / SO2, making them highly selective for CO and eliminating false alarms.
