Description
CO2 transmitters for indoor air quality and energy efficiency applications. The ambient or duct mounted CO2 transmitters with junction box offer accuracy and fast/ simple connection to our Wireless sensor device with DB18 VDC/ mA input module in our wireless logging and monitoring systems. CO2 measurement range of 0-2000 PPM at an accuracy of +-3% of reading. For CO2 measurements, an infrared/ gas sensing engine accurately monitors CO2 content. The sensor design is based on the absorption of light in a reflective light pipe or wave guide diffusion gas chamber. Light is absorbed in proportion to the CO2 concentration and the remaining light is measured and converted into an analog signal. A gas permeable, water resistant diffusion filter prevents particulate and water contamination of the sensing probe. The Model SC18 wireless transmitter can handle up to four (4) CDP-1 probes or combination of our compatible external sensors.
