CDL carbon dioxide sensors maximize energy savings, while ensuring optimal ventilation. The sensors allow ventilation systems to be controlled by the amount of CO2 present in a space. The CDL Series detect fluctuations in CO2 levels and signal ventilation systems to provide an inlet of fresh air optimal for the space at a given time saving energy and ensuring tenant comfort. APPLICATIONS Controlling ventilation in response to occupancy Facilitating compliance with ASHRAE 62.1 standard for air quality Office buildings, conference rooms, schools, retail stores, etc. Microprocessor design increases accuracy and reduces installation time Non-dispersive infrared technology (NDIR) repeatable to ±20 ppm ±1% of measured value Innovative self-calibration algorithm...easy to maintain 5-year calibration interval (recommended) Low ambient sensitivity Field-selectable outputs for operation flexibility Revolutionary direct duct mounting design Integrated transducer and probe...eliminates the need to install a separate pick-up tube Snap-on faceplate...no screws required, making installation and service a snap Adjustable duct probe...simplifies installation and airflow monitoring CO2, humidity, and temperature sensing all in one compact device...fewer units to buy and install
