The MTECH 700-100 Visibility Sensor is a highly reliable, compact and rugged atmospheric visibility sensor. It combines new digital signal processing with the proven reliability of the very successful previous analog model.
The sensor can be used to replace existing transmissometers, while providing better stability, accuracy and maintainability, at a much lower price. Applications include visibility measurements at airports, lighthouse, along highways and on ships, as well as for meteorological observations. The sensor can also be used in the detection of hazards to transportation caused by fog, snow, smoke, blowing sand, etc. The Model 700-100 uses the Forward Scatter Principle to measure the atmospheric extinction coefficient and visibility. A high intensity Xenon strobe transmitter is used to illuminate the sensor¡¯s scatter volume. This results in a high signal-to-noise ratio and reduces the effects of natural background light variations.
Accurate visibility measurements are possible over a standard range of 0.01 to more than 30 miles, the widest dynamic range available. The use of light within the visible spectrum allows the sensor to most accurately simulate human perception of visibility.
