0-2000ppm measurement range, Dual 4-20mA outputs, 1 year warranty. CE.

CWVS2XX1 $506.00 EA

  • Overview
  • Series Specifications
The CWV Series is a non-dispersive infrared analyzer designed for measuring CO2 concentration in office and living spaces. Its 2000ppm 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.

  • 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
Microprocessor design reduces long-term drift and calibration requirements
