The AeroCone Rain Collector reduces wind-induced errors by providing a more aerodynamic path around the collector. The design improves rain data accuracy in high wind situations where the horizontal wind velocity can cause under reporting.
Product Details

The AeroCone Rain Collector is designed to meet the guidelines of the World Meteorological Organization. Rain enters the collector cone, passes through a debris-filtering screen, and collects in one chamber of the tipping spoon. The spoon tips when it has collected an amount of water equal to the increment in which the collector measures (0.01" or 0.2 mm). As the spoon tips, it causes a switch closure. The rain water drains out through the screened drains in the base of the collector.

The collector is designed for years of accurate, trouble-free service. The shape is aerodynamically designed to minimize rainfall catch reduction caused by high winds. The body and base of the collector are constructed of tough, UV resistant plastic.

The 260-6466 Rain Collector comes with a mounting base that can be mounted to a pole or post. The 260-6464 has a flat surface mount. The 260-6466M and 260-6464M are factory-calibrated to report 0.2 mm per tip.
