The T-200 rain gauge was developed 25 years ago to monitor rainfall in all weather. It was designed in collaboration with the Norwegian Meteorological Institute and the Norwegian Institute of Geotechnical Engineering. Precipitation can be reported in real time at any interval to calculate intensity. The precipitation gauge is easy to configure, works with automatic data acquisition systems, and has 0-5 V or SDI-12 output options.

The original T-200B had a capacity of 600 mm (24 in) and was fitted with a vibrating string sensor. Geonor now offers 1000 mm (40 in), 1500 mm (60 in) and 3000 mm (120 in) precipitation -- rain gauges, and can be combined with three sensors. The manometer has a protective housing with WMO standard 200 cm2 inlet.

Precipitation is measured using a vibration line load sensor. Instruments and windshields are mounted on the base. With antifreeze, any solid sediment will melt in the container. As a result, no electric heating is required, thus eliminating a common source of error. Add a thin layer of oil to prevent any evaporation.
