Ideal for any setting where CO levels in breathing air need to be monitored, the CO-Guard is designed to be simple. This compact sensor is easy to install, is pre-calibrated, and lasts up to three years.
By keeping the design of the CO-Guard simple, ENMET provides an easy-to-use sensor that monitors air and meets requirements for Grade D breathing air. The most common application for the CO-Guard is monitoring breathable air while applying wood finishing or paint spray, although it can easily be used in other settings.
