DESCRIPTION
The CWV Series is a non-dispersive infrared sensor designed for measuring CO2
concentration in office and living spaces. Its 2000 ppm measurement range makes it
an ideal solution for meeting ASHRAE and other ventilation control standards.
The CWV Series features multiple output options, microprocessor-based digital
technology, and a unique self-calibration algorithm which improves long-term
stability and accuracy.
APPLICATIONS
● Controlling HVAC in response to occupancy – save energy by providing
ventilation only as required
● Improving tenant comfort
● Schools, museums, airports, commercial buildings, etc.
● OEM applications
● Home automation
●
Big-box retail
● Restaurants
● C-Stores
● Bid/Spec market
