CO-D4 Carbon Monoxide Sensor

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

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

Alphasense CO-D4 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 sensors in the Alphasense portfolio. They are designed for handheld, clip-on and wearable instruments where space in the analyzer is limited. These CO-D4 sensors come standard with a chemical filter to reduce cross-sensitivity to common interfering gases.
