Product details:

A tunnel is a special tubular structure. With the increase of traffic volume, the concentrations of smoke, diesel exhaust, and carbon monoxide continue to rise. They not only pose a threat to the environment, but also affect the visibility inside tunnels. If not discharged in a timely and reasonable manner, they will directly pose a danger to personnel and traffic.

RegalTunnelVICO740It is designed for online collection of data within tunnelsVI/COProvide data to traffic monitoring departments to provide reliable basis for tunnel ventilation and road traffic.VIThe analyzer is emitted by/Composed of a receiving unit and a reflecting unit. installation distance3Rice or10Meter, the total optical path length after reflection is6Rice or20Rice. The light beam is attenuated by dust, and the signal is obtained and processed by the evaluation unit into a measurement value. The analyzer will automatically compensate for the effects of pollution and long-term drift.COUsing negative gas absorption correlation method, to be determinedCOInfrared absorption spectrum wavelength4.5-4.9Micro sizedCOMeasure by absorption peakCOConcentration.

Regal Tunnel VICO 740The detector is not affected by environmental interference light and has self checking and automatic calibration functions
