The Nuvair Pro CO2 alarm analyzer with relay in waterproof box measures carbon dioxide levels in all breathing gas mixes and is designed to verify CO2 concentration in stored gas cylinders, monitor an enclosed space, or analyze continuous flow gas from a compressor. Mounted in a weatherproof box, the analyzer is moisture and impact resistant and is compatible with outdoor and marine environments. This unit is equipped with a loud piezo alarm, an alarm light, and an SPDT relay (10A @ 230VAC/30 VDC) to control compressors or other accessories.
Two audible and visual alarms for low and high carbon dioxide content can be set by the user. If the alarm sounds, the analog output can activate an optional relay that shuts down compressors automatically, sounds remote alarms, or activates emergency backup systems.
