Wall Mount CO2 /Temp Sensor with out display,0/2-10Vdc or 0/4-20mA output. Overview The C7262 Sensor is a stand-alone carbon dioxide (CO2) and temperature sensor for use in determining ventilation necessity with HVAC controllers. The C7262 measures the CO2 concentration and temperature to control the amount of fresh outdoor air supplied to maintain acceptable levels of CO2 in the space. Features Used for CO2 based ventilation control. Integral 20K ohm NTC temperature output. Models available with LCD that provides CO2 ppm level. Non-Dispersion-Infrared (NDIR) technology used to measure carbon dioxide gas. 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.
