VERIS CWLSXTHX3F CO2 Sensor. New In Factory Sealed Package. Free Shipping.

Description

CWL 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 CWL 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 62.1-2004 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
