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.
