Ax60+ CO

Carbon Monoxide Monitoring System

Carbon monoxide monitoring with the Ax60+ CO

The Ax60+ CO is designed to protect personnel in environments where carbon monoxide (CO) may be present, including plant rooms, parking garages, and other enclosed spaces where gas can accumulate.

It can also be used for online cylinder filling applications, helping to protect divers from compressed air contaminated with carbon monoxide, whether caused by compressor maintenance issues or contamination at the compressor inlet.

Flexible system integration

The Ax60+ CO can operate as a standalone sensor with integrated alarm functionality or as part of a wider Ax60+ system supporting up to four sensors.

Within a multi-sensor setup, the system can be combined with Ax60+ oxygen (O₂)/SAFE-OX and carbon dioxide (CO₂) sensors, allowing it to support a range of application requirements within a single platform.
