Carbon Dioxide sensor/Transmitter

Carbon Dioxide /CO2 sensor/Transmitter/Controller 

 
Application
This carbon dioxide transmitters/controllers are designed for monitoring and controlling environment of industry and commercial buildings. They can be used in working house, clean room, laboratory, machine room, office, airport, parking lot, station and museum, etc. where air quality control is necessary. CDW series is suitable for wall mount installing while CDD series is suitable for duct mount installing.

Features
● High performance NDIR digital sensor and circuit, ensure precise measurement and temperature compensation
● Stable and reliable
● 15 years sensor life without maintenance
● Fast response
● Light and state of art housing, easy installation and wiring
● Multiple output selection
● The MMI can set parameters and calibrate output, so that the product becomes a alone controller
