C7233 CO2 Sensor, No Display (Wall Mount)

Image depicted is of the C7233A1008 model with display. The C7233A1016 model does not feature a display. The C7233 Series Sensors are stand-alone carbon dioxide (CO2) sensors for use in determining ventilation necessity with HVAC controllers. The C7233 measures the CO2 concentration in the occupied space. C7233 sensors are used in ventilation systems to control the amount of fresh outdoor air supplied to maintain acceptable levels of CO2. Product Features: Wall mount Ultra compact size and elegant design with easy cleaning with smooth front membrane Options with or without white LED displays - all variants have red LED notification activated when CO2 level exceeds preset threshold Analog output range is selectable 0/2-10 Vdc, 4-20mA and provides accurate proportional linear signal through entire sensing range 0-2000ppm Highly accurate and reliable non-dispersion infrared (NDIR) technology for CO2 sensing Programmable SPST Relay (1A@50VAC/24VDC)
