This durable weather instrument for monitoring rain rate and total rainfall, with minimal care, will provide you with the rainfall data you are looking for. The raingauge was designed to provide a low-cost, reliable, industrial, tipping bucket rain gauge. Its simple design assures trouble-free operation, yet provides accurate rainfall measurements. It has a 8" collector and is shipped with all mounting equipment. The tipping bucket sensor mechanism activates a sealed reed switch that produces a contact closure for each 0.01", 0.2 mm or 1 mm of rainfall. The rain gauge sensor can be pole mounted or bolted to a level plate.
Datalogging is done with Optimum Instruments DD-310R datalogger. The data logger connects to the rainfall gauge through a pulse input channel and records tips from the rainguage.

Installation
Consists of attaching the tree sensor support legs to a firm platform or securing the side bracket to a stable vertical structure.
Calibration
Gauges are typically calibrated biannually by Optimum Instruments rain gauge calibration facility just prior to installation in the spring and prior to storage in the fall. A complete calibration report is generated for each calibration run. Field maintenance should include occasional cleaning of the collector screen and inspection of the internal mechanism to make sure it is free from insects and debris.
