DESCRIPTION

The CWV Series is a non-dispersive infrared sensor designed for measuring CO

concentration in oce 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
