Wall/Duct Mount Carbon Monoxide Transmitter in house air clean and park station.
Applications & Features
It is 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 many similar sensors, it gives more than 5 years sensor life to protect customer’s investment
Better than many 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 interference capability
Wide range of operating temperature
Light and state of art housing, easy installation
Optional relay output to actuate the alarm or control function
The MMI can set various parameters, calibrate and adjust output, so that the product can be a stand alone controller
