HOBO Data Logging Rain Gauge
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 160 inches of rainfall data that can be used to determine rainfall rates, times and duration.
Software and Communications
The HOBO Data Logging Rain Gauge requires either of the following to connect to the computer:
- Pendant Optic USB Base Station & Coupler (part # BASE-U-1)
- Optic USB Base Station (part # BASE-U-4)
- HOBO Waterproof Shuttle (part # U-DTW-1
Features
- Blinking LED inside logger case confirms operation
- User-replaceable battery lasts 1 year (typical)
- Nonvolatile EEPROM memory retains data even if battery fails
- Constructed from field-proven corrosion-resistant components: aluminum housing and collector ring; stainless steel shaft and brass bearings; tipping bucket is high-precision, injection-molded, high-impact ABS plastic.
- Removable top for easy data offload
- Fully integrated HOBO Pendant Event data logger
- Battery check at launch
- Programmable start time/date
- Three mounting feet to use on flat, level surfaces (three screws included)
- Side bracket for mast mounting (hose clamps included)
