Meteorological Sensors

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.
