A wall mount, non-dispersive infrared (NDIR) sensor designed for measuring environmental CO2 concentration in indoor living spaces.
A wall mount, non-dispersive infrared (NDIR) sensor designed for measuring environmental CO2 concentration in indoor living spaces.
Designed for measuring CO2 levels in living spaces, the CWV2 is ideal for use with Building Automation Systems (BAS) controllers that accept 4 to 20mA, 0 to 5 VDC, or 0 to 10 VDC outputs. Measuring CO2 levels from 0 to 2000 ppm, this air quality sensor has an accuracy of ±40 ppm ±5.5% of the measured value and is ideal for bid-spec applications.
