33ZCSPTCO2LCD-01
The indoor air quality CO2 sensor uses infrared technology to measure the levels of CO2 in the air. These levels can be used as input to a Carrier controller to control the ventilation damper position and ensure an adequate level of outside air in the building.
The Carrier 33ZCSPTCO2LCD‑01 indoor air quality sensor measures carbon dioxide levels to support effective ventilation control. Its LCD display, infrared sensing technology, and flexible output options make it well suited for commercial HVAC applications where consistent indoor air quality monitoring is required.
Infrared sensing technology delivers stable, accurate CO₂ readings over time. Automatic background calibration helps maintain performance without frequent recalibration, supporting dependable indoor air quality monitoring throughout the life of the sensor.
Multiple output options allow the sensor to interface easily with Carrier controllers and ventilation dampers. Compatibility with standard junction boxes and a terminal-block mounting plate help streamline installation in both new construction and retrofit applications.
The Indoor Air Quality CO₂ Sensor provides accurate CO₂ monitoring with clear on-screen readings and flexible outputs for dependable HVAC ventilation control.
