Onset Data Logging Rain Gauge

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.

Features:

* A high quality tipping-bucket rain gauge includes a HOBO Pendant Event data logger.
* 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 rain shield
* Available in Metric or Imperial
