Recommended tunnel VICO detector

Tunnel VICO detector, model FT-SDN1, brand Fengtu Technology, this is an instrument launched by Fengtu to detect VI/CO data inside the tunnel. VI/CO refers to visibility and carbon monoxide, which can be used by traffic authorities to collect data and use it to inform decisions on tunnel ventilation and road safety.

This product works according to the transmission principle and comes with compensation function, which can automatically compensate the gain of the optical lens in the case of contamination, thus extending the maintenance period.

Because the tunnel is a relatively closed space, the exhaust gas from the vehicle can not be discharged in time, it is easy to lead to carbon monoxide and particulate matter accumulation, affecting visibility and driver safety. And with too much carbon monoxide, it's toxic. Therefore, VICO detectors need to be installed in the tunnel to monitor the visibility and carbon monoxide concentration in the tunnel in real time. It's all about safe departure.

FT-SDN1 tunnel VICO detector adopts wall mounting mode, measuring range is 0--35×10-3 1/m, CO is 0--500PPM, accuracy is ±0.0001 1/m, CO is ±1. Measuring distance is 6 meters optical path (probe mounting distance is 3 meters).

It has the following advantages:
1, high resolution measurement visibility data;
2, not affected by other stray light sources;
3, specially designed for the harsh environment of the tunnel, can effectively avoid the environment, passing vehicles caused by vibration can not be measured;
4, the instrument has fault alarm function, can automatically store data;
5, with a variety of data output methods;
6, microprocessor technology, fully digital operation.
