Duct Mount CO2 Sensor with no display,0-10 Vdc (fixed) output. Overview CO2 Sensors offer a fixed 0-2000ppm & fixed 0-10Vdc output, determine ventilation need with HVAC controllers and measure CO2 concentration in ventilated spaces or ducts. Used in ventilation & AC systems to control the amount of outdoor air supplied. Features Non-Dispersion-Infrared (NDIR) technology used to measure carbon dioxide gas. Gold-plated sensor provides long-term calibration stability. Fixed 0-2000ppm, fixed 0-10Vdc output. Used for CO2 based ventilation control (Demand Control Ventilation (DCV)). Automatic Background Calibration (ABC) algorithm based on long-term evaluation reduces required typical zero-drift check maintenance.
