CO-D4X Carbon Monoxide Sensor

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

Miniature CO detection for safety-critical monitoring and process control.

Alphasense CO-D4X sensors provide high-performance, miniature-sized carbon monoxide detection for portable, fixed and wearable gas monitors across industrial safety and air-quality applications.

These D-series sized, CO sensors are the smallest industrial-safety CO sensor in the Alphasense portfolio. They are designed for handheld, clip-on and wearable instruments where space in the analyzer is limited. These CO-D4X sensors come standard with a chemical filter to reduce cross-sensitivity to common interfering gases. In addition, the CO-D4X comes standard with a filter 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-D4X sensors are recommended for wearable and portable systems, where interferent gases like H2 / H2S / NO2 / NO / SO2 are present and a robust CO measurement is required.
