Meteorological Sensors – OTT

OTT meteorological sensors allowing users access to meteorological data with unmatched accuracy. Our OTT precipitation and present weather sensors complete your network of surface weather and water level monitoring stations. In addition to high accuracy precipitation measurement, our stations can also measure humidity and wind.

OTT WAD 200/314 - Weighing Rain Gauge

The OTT WAD 200/314, a liquid precipitation measuring instrument that combines the advantages of a tipping & weighing system, is specially designed for the use in subtropical and tropical climates. The highly sensitive measuring principle of the precipitation meter meets the requirements of the WMO guidelines and delivers accurate measured values in real time for both quantity and intensity of liquid precipitation in the range of 0.001 to 720 mm/h.

The rain gauge has a low power consumption and is an accurate measuring instrument even under extreme weather conditions. A usually prescribed annual calibration can be carried out with the aid of a reference weight and is therefore more accurate than the usual calibration procedure using water volume.

OTT Parsivel² - Laser Weather Sensor

The OTT Parsivel² is a modern laser disdrometer for comprehensive measurement of all precipitation types. The Parsivel² captures both the size and speed of falling particles, classifying them into one of 32 separate size and velocity classes. The raw data are used to calculate the type, amount, intensity and kinetic energy of the precipitation, the visibility in the precipitation, and the equivalent radar reflectivity

OTT Pluvio² L – Weighing Rain Gauge

The OTT Pluvio² L is an all-weather precipitation gauge that uses superior weight-based technology to measure the amount and intensity of rain, snow, and hail. Developed in conjunction with industry-leading meteorological services, the OTT Pluvio² L employs a high-precision load cell and algorithms that compensate for wind, temperature, and evaporation, ensuring the highest accuracy precipitation measurements over time.

OTT Pluvio² S

The OTT Pluvio² S weighing precipitation gauge measures the intensity and cumulative precipitation in a broad measuring range from 0 to 3,000 mm/h. The professional rain gauge is a further development of the tried-and-tested OTT Pluvio², with state-of-the-art technology in a compact design that captures up to 400 mm of precipitation on a collecting area of 200 cm². It is virtually maintenance-free, fits onto 2-inch pedestals, needs little space and can replace conventional rain gauges or tipping buckets without any structural work
