Description
Catatan hingga 160 inci curah hujan dengan kecepatan sampai 12,7 cm (5 inci) per jam. Sistem Data Logging Rain Gauge bertenaga baterai dan dilengkapi dengan data log peristiwa HOBO® Pendant Event dengan alat pengukur hujan tip. Mudah mengumpulkan data curah hujan, waktu, dan durasi, serta suhu saat digunakan dengan perisai radiasi opsional (RS1 Solar Radiation Shield, atau M-RSA). Stasiun pangkalan atau antar jemput diperlukan.
Feature
- High quality tipping-bucket rain gauge includes a HOBO Pendant Event data logger. Base station or shuttle is required.
- Time and date stamp is stored for each tip - provides detail needed to determine rainfall rates and duration.
- Reliable, field-proven rain gauge.
- Compatible with HOBOware and HOBOware Pro software for logger setup, graphing and analysis.
- Also records temperature when used with an optional solar radiation shield.
Spesification
Rain Gauge

Calibration: Requires annual calibration: can be field calibrated or returned to the factory for re-calibration
Operating temperature range: 0° to +50°C (+32° to +122°F)
Storage temperature range: -20° to +70°C (-4° to +158°F)
Environmental rating: Weatherproof
Housing: 15.24cm (6-in.) aluminum bucket
Tipping bucket mechanism: Stainless steel shaft with brass bearings
Dimensions: 25.72 cm height x 15.24 cm diameter (10.125 x 6 in.); 15.39 cm (6.06 in.) receiving orifice
