Analox A50
Wall-mounted CO2 Detector

Local municipalities and government agencies worldwide have instituted standard practices and regulations designed to protect workers in almost every working environment. One of the most talked about requirements is the installation of carbon dioxide (CO2) testing and monitoring devices. 

The Analox A50 carbon dioxide detector is a fixed CO2 monitoring device that is simple to install, operate and keep employees protected from the potential dangers of increased CO2 exposure in the workplace

The A50 is designed to be mounted on a wall in a confined area that is being monitored. The unit scans for ambient levels of CO2 and sounds both audible and visual alarm warning when elevated levels of carbon dioxide are detected. 

Typical places where the A50 is most effective are CO2 cylinder storage areas in restaurants, bars, cellars and fast food outlets. Specific areas most vulnerable to CO2 leaks are facilities with drink dispensers or beer pumps. 

While the food and beverage industry is a prominent user of A50 monitors, other industries needing cost efficient and effective CO2 detectors include medical laboratories and related facilities, fire suppression operations, schools and academic facilities and companies involved with green energy and environmental testing.

NOTE: Facilities requiring CO2 testing and analysis in the United States and Canada should investigate Analox’s popular AX60+. The AX60+ offers additional features and monitoring to better meet the standards and practices required in those particular countries.
