CO Sensor

The carbon monoxide transmitter is specially designed for ventilation applications in buildings where motor vehicles are stored. It adopts electrochemical sensor technology imported from the UK, which guarantees 6-year service quality. While delivering a cost-effective solution for users, it also offers an optional on-site display function.

It can be integrated into ventilation and air conditioning systems for the following applications:
Commercial complexes
Hotels, cinemas and museums
Underground parking lots
Domestic gas alarm systems
