Record up to 160 in. of rainfall at rates up to 12.7 cm (5 in.) per hour. The Data Logging Rain Gauge system is battery powered and includes a HOBO Pendant Event data logger with a tipping-bucket rain gauge. Easily collect rainfall, time, and duration data, as well as temperature when used with an optional solar radiation shield (RS1 Solar Radiation Shield, or M-RSA). Base station or shuttle is required.
Rain Gauge

Temperature Measurement
Measurement range: -20° to 70°C (-4° to 158°F)
Accuracy: ± 0.47°C at 25°C (± 0.85°F at 77°F). A solar radiation shield is required for accurate temperature measurements in sunlight.
Resolution: 0.10°C at 25°C (0.18°F at 77°F), see Plot A on page 10.
Drift: Less than 0.1°C/year (0.2°F/year)
Response time: Airflow of 1 m/s (2.2 mph): 10 minutes, typical to 90%
