Overview

A battery-powered rainfall data collection and recording system that includes a  HOBO Pendant Event data logger integrated into a tipping-bucket rain gauge. This model automatically records up to 3200 mm of rainfall data, which can be used to determine rainfall rates, times, and duration. Also records temperature when used with an optional solar radiation shield (RS1 Solar Radiation Shield or M-RSA). A base station or shuttle is required.
