Fitur
- Pengukur hujan berkualitas tinggi dengan pencatat data HOBO Pendant Event.
- Waktu dan tanggal disimpan untuk setiap tip – memberikan detail yang diperlukan untuk menentukan tingkat curah hujan dan durasi.
- Pengukur hujan yang andal dan terbukti di lapangan.
- Kompatibel dengan perangkat lunak HOBOware dan HOBOware Pro untuk pengaturan, grafik dan analisis logger.
- Merekam suhu saat digunakan dengan pelindung radiasi matahari opsional.
Spesifikasi
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
