Carbon dioxide gas (CO2) is a component of the earthΓÇÿs atmosphere. Although carbon dioxide is invisible and odorless, an increased CO2 content in the indoor air leads to fatigue and reduced concentration for humans.In rooms with high occupancy, such as conference rooms and theatres, the negative effects on humans becomes all the more evident.The SCD-P series duct mount transmitters are designed for the measurement of Carbon Dioxide (CO2) in Heating Ventilating and Air Conditioning applications where Demand Control Ventilation (DCV), fresh air and indoor Air Quality (IAQ), and rooftop air handling economizer control systems are often required.The SCD-Pxxxx sensors incorporate the a dual wavelength NDIR CO2 sensor, which compensates for ageing effects, is highly insensitive to pollution and offers outstanding long term stability.The SCD-Pxxxx Transmitter is available with CO2 output 0-10 V or 2x 0..10 V (CO2 + temperature), optional with passive temperature sensor. CO2 DUCT SENSOR, 0-2000 PPM, 0-10V OR 4-20MA SELECTABLE OUTP
