CO₂ Sensors

Carbon dioxide is the most significant contributor to global warming. APC Smartwave’s CO₂ level monitoring sensors are used for the continuous monitoring of CO₂ levels in their surrounding environment, confined spaces, inert storage areas or where low or high levels of CO₂ may pose a hazard to personnel and the environment.
