CS125 Present Weather Sensor
1. Introduction
The CS125 is an infrared forward scatter present weather sensor for automatic
weather stations including road, marine and airport based stations. The CS125
uses the well-established forward scatter system for visibility measurement,
utilising a 42º scatter angle. The CS125 uses high speed sampling to reduce
missed events such as rain and hail and improves response to other suddenly
changing conditions. When an optional CS215 temperature and RH sensor is
connected, the CS125 can distinguish wet and dry obscuration (for example mist
and haze) and make more precise discrimination between liquid and frozen
precipitation.
