HOBO Rain Gauge (Metric) Data Logger
Product Options
Overview
The Data Logging Rain Gauge is a battery-powered rainfall data collection and recording system which 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 that 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.
