Visibility Co / VI detecto

  Shanghai Xunfei xfts -- vico80 tunnel environmental detector is a product that collects - carbon oxide / nitrogen oxide and visibility data in the tunnel
The detector is installed on the side wall of the tunnel, and the collected data are provided to the traffic supervision department at the first time to provide a reliable basis for tunnel ventilation and operation
The V1 analyzer is composed of transmitting / receiving unit and reflecting unit
The light beam is attenuated by dust, and the obtained signal is processed into the measured value by the evaluation unit
CO and no adopt negative gas absorption mode, and the concentration is measured by the absorption peak of specific spectral wavelength
The detector has its own status display, and has self inspection and automatic calibration functions, which can ensure accurate measurement values

  Xfts-vico800 can be expanded to add NOx detection according to different customer needs
