Features  

• Used for CO2 based ventilation control. 

• Models available with LCD that provides sensor readings and status information. 

• Non-Dispersion-Infrared (NDIR) technology used to measure carbon dioxide gas. 

• Gold-plated sensor provides long-term calibration stability. 

Device provides voltage or current output based on CO2 levels. 

• Models available with SPST relay output. 

• Automatic Background Calibration (ABC) algorithm based on long-term evaluation reduces required typical zero-drift check maintenance.
