Product Overview
The CWV2 air quality sensor for living space is for use with BAS controllers designed to accept 4 to 20mA,
0 to 5 Vdc or 0 to 10 Vdc outputs. This sensor measures CO2 levels using a dual-beam, non-dispersive infrared (NDIR)
technology.
The CWV2 Value sensor with an accuracy of ±40 ppm ±5.5% of measured value, is ideal for bid-spec applications.
