Deskripsi

Overview

Sistem pengumpulan dan pencatatan data curah hujan bertenaga baterai yang mencakup pencatat data HOBO Pendant Event yang diintegrasikan ke dalam penakar hujan tipping-bucket. Model ini secara otomatis mencatat curah hujan hingga 160 inci dengan kecepatan hingga 12,7 cm (5 inci) per jam. Mengumpulkan data curah hujan, waktu, dan durasi dengan mudah, serta suhu saat digunakan dengan pelindung radiasi matahari opsional (Pelindung Radiasi Matahari RS1 atau M-RSA). Diperlukan stasiun pangkalan atau pesawat ulang-alik.

Features

  • 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
