FD70 is powerful technology that can potentially replace many separate sensors such as your visibility and present weather sensor, rain gauge, disdrometer, and freezing rain sensor. It can also outperform them in delivering highly accurate visibility and precipitation reporting in all weather conditions, as well as unsurpassed detection sensitivity and reliable identification of present weather.
The FD70 is engineered to meet WMO SYNOP reporting guidelines for precipitation and obscuration types. Its sensors excel with fast response times and the highest sensitivity to correctly detect and identify individual droplets. They provide accurate visibility measurement with proven calibration traceability and a range of up to 100 km (62 mi) and are the first sensors on the market that can reliably report a full range of present weather types including freezing precipitation.
