IMPORTANT: Requires Hoboware Free or Hoboware-Pro software for proper operation. Also requires a Shuttle (with Hoboware-Pro), USB Base Station or USB Base Station for Pendant

The Data Logging Rain Gauge is a fully self-contained 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.

Features

– Self-contained rainfall logger includes a HOBO Pendant Event data logger with a high quality tipping-bucket rain gauge
– Time and date stamp is stored for each tip – provides detail needed to determine rainfall rates and duration
– Reliable, field-proven rain gauge
– Also records temperature when used with an optional radiation shield
