Brand:SODI
Model:CVD-NO
SODI CO/VI/NO detector is specially used for highway tunnel environment monitoring, which detect the carbon monoxide, nitric oxide concentration and coefficient of visibility, it can maintain the all-weather real-time detection of tunnel CO/NO concentration coefficient and visibility. After testing data processing to the tunnel management computer system with monitoring system analysis, so as to timely put forward the best monitoring and tunnel ventilation fan operating plan. CO/VI/NO detector should have very strong self-checking function, CO/VI/NO real-time online monitoring the working state of the detector, when its failure to operate, it will be alarmed immediately .
Characteristics and Advantages：
1. Flexible configuration, carbon monoxide, nitric oxide, visibility range can be arbitrary configuration and unit, etc.;
2. Installation is simple - the only connection mouth;
3. Interface variety - 4～20mA or 0～20mA，RS232 interface, relay interface, etc.;
4. High reliability - as long as a moving parts, testing operation, reliable and continuous surface maintenance design;
5. High precision - rapid, accurate, continuous automatic determination of co concentration, nitric oxide, transmittance parameters, leading the market of patented technology;
6. Custom function - measuring values led real-time display function, can expand the function of nitrogen oxide
