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 and controller are 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 most other similar sensors, it gives more than 7-10 years sensor life to protect customer’s investment
Better than most other similar sensors which maybe need recalibration every 6-12 months, it only need periodical recalibration as long as 3-5 years or more, maintain 5% accuracy
All electrical terminals are on the inside bottom, avoid any possible destroy to PCB when wiring (for CMWN)
