• 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
• Raliable, field-proven rain gauge
• Also records temperature when used with an optional radiation shield
• Constructed from field-proven corrosion-resistant components: aluminum housing and collector ring; stainless steel shaft and brass bearings; tipping bucket is high-percision, injection-molded, high-impact ABS plastic
• Three mounting feet to use on flat, level surfaces (three screws included)
• Side bracket for mast mounting (hose clamps included)
• 15.4 cm (6.06 in.) collector ring
• Self-emptying for continuous rainfall logging

Memory:
64K; number of data points depends on rainfall rate
16K to 23K tips when recording rainfall only
25K to 30K tips and temperature measurements when recording both

Battery life:
1 year (typical) user-replaceable

Rainfall
Range: Up to 320 cm (RG3-M), up to 16 in. (RG3)
Resolution: 0.2 mm (RG3-M), 0.01 in. (RG3)
Time stamp resolution: 1 second
Calibration accuracy: +/- 1.0% (up to 20 mm/hr [RG3-M], 1 in/hr [RG3])
