The Model 50202 Precipitation Gauge accurately measures rain or snow precipitation without moving parts. Insulated housings and thermostatically controlled heaters permit operation at temperatures below freezing. Unlike conventional tipping-bucket and weighing gauges the 50202 has no moving parts, making the instrument ideal for use on moving platforms such as buoys and ships. Precipitation measurement is made with a capacitive transducer and electronic circuit that produces a voltage output. Total precipitation can be tracked by a datalogger or recorder
