CO2 sensors

CO₂ sensors are electronic devices that measure the concentration of carbon dioxide (CO₂) in the air. At Ocean Controls, our CO₂ sensors are designed for accurate, real-time monitoring of indoor and outdoor air quality. These sensors are essential for HVAC systems, building automation, greenhouses, classrooms, and industrial safety applications. By continuously tracking CO₂ levels, they help optimize ventilation, reduce energy costs, and ensure healthy air for occupants.
