DESCRIPTION

The CWV Series is a non-dispersive infrared sensor designed for measuring CO2 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

AIR QUALITY

● Restaurants

● C-Stores

● Bid/Spec market

CWV

FEATURES

● Microprocessor-based design reduces long-term drift and

calibration requirements

● Non-dispersive infrared technology (NDIR) repeatable to ±30 ppm ± 4.5% of

measured value...high accuracy measurements

● Innovative self-calibration algorithm...easy to maintain

● 5-year calibration interval (recommended)

● Low ambient sensitivity

● Improve comfort and facilitate compliance with ASHRAE 62.1 standard

for air quality

● Demand control ventilation provides reduction in energy costs...helps with

green branding initiatives

● Dual analog outputs...added user convenience

● LED indication for power and error detection...reduces

time spent troubleshooting

● Switchable 0-3/5/10V output...increased exibility

● US & European mounting holes...installation exibility

● Field calibratable...reduce costly downtime

● 4-20mA and voltage outputs in one unit...greater versatility
