It’s necessary to control the ventilation of car park and vehicle maintenance and test work shop according to many building HVAC regulations. Considering of energy efficiency, demand controlled ventilation (DCV) is recommended to provide enough fresh air according to CO concentration and temperature. CM transmitter/controller is designed for these applications. It can effectively control the ventilation system to safety and energy-saving operations
 Environmental friendly electrochemical sensor gives good long term accuracy, sensitivity and reliability
 Better than other similar sensors, it gives more than 5 years sensor life to protect customer’s investment
 Better than other similar sensors, it only need periodical recalibration as long as 3 years or more, maintain 5% accuracy
 Digital technology applied, multiple outputs optional, over voltage and reverse polarity protection, high reliability and anti-interference capability
 Light and state of art housing, easy installation
 Wide range of operating temperature, optional relay to actuate the alarm or control function output
 The MMI can set various parameters, calibrate and  adjust output, so that the product can be a standalone controller
