Degreane - Model T220 - RVR Transmissometer Sensor Brochure

The TR30LED transmissometer is a sensor used for visibility measurement for aeronautical applications. It measures the Transmissive Ability of the Atmosphere (TAA) and calculates Meteorological Optical Range (MOR). Runway Visual Range (RVR) is processed using transmissivity ability of atmosphere (TAA), luminance (LU320) and runway lighting intensity measurement.
