Rain Collector Designed to meet the guidelines of the World Meteorological Organization, our self-emptying tipping-bucket design is exceptionally accurate. Used to display daily and accumulated rainfall on our weather stations as well as rate of rainfall when available on select weather stations. Record rain data and transmit rainfall information using an Anemometer/Sensor Transmitter Kit (#6332), sold separately. Comes with 40′ (12 m) standard cable. This rain collector must be mounted on a flat surface. Rain collector can be user-calibrated for 0.01″ or 0.2 mm. Also available with factory-calibrated 0.2 mm rain collector. If you’d like to mount your rain collector on a pole or other surface, try our Rain Collector (#7857) for Vantage Pro2.
