NSA-A/CO2-DUCT

The Carrier Carbon Dioxide Duct Series monitors the carbon dioxide (CO₂) levels in industrial, commercial, school, and office-type environments. The concentration of CO₂ is a strong indication of the overall indoor air quality. The NSA-A/CO2-DUCT Series is based on a single beam, non-dispersive infrared technology and is a cost-efficient solution for measuring carbon dioxide levels for building climate control.

Applications

Schools, Office Buildings, Auditoriums, Gymnasiums, Shopping Malls, Theatres, Demand Control Ventilation & Economizers
