Deskripsi
Mengukur curah hujan secara akurat dengan HOBO Pendant Event Data Logger. Tentukan tingkat curah hujan, waktu, dan durasi setelah pemasangan. Secara efisien mengumpulkan dan menyimpan data. Selain itu, dapatkan akses ke data acara terperinci. Data disimpan secara langsung agar penggunaan memori menjadi lebih baik. Gunakan pelindung radiasi matahari untuk pengukuran suhu yang akurat dalam aplikasi sinar matahari (produk: RS1 Solar Radiation Shield dan M-RSA (pre-assembled) Solar Radiation Shield).
Fitur Unggulan
- Rekam curah hujan dengan tipping-bucket rain gauges
- Merekam suhu tanpa melakukan kontak
- Penyimpanan data berbasis peristiwa menyediakan data terperinci dan penggunaan memori yang efisien
- Menyimpan lebih dari 16.000 tips (curah hujan 160 in. Dengan pengukur hujan 0,0 in.)
Untuk pencatat curah hujan secara manual, lihat HOBO RG3 yang mencakup pencatat data yang diintegrasikan ke dalam alat pengukur curah hujan.
Spesifikasi
External Event Input
Event sensor: Two-wire interface suitable for measuring mechanical and electrical contact closures
Maximum input frequency: 1 Hz (1 pulse per second)
Lockout time: 500 ms
Minimum pulse width: 1 ms (hardware debounce)
Input/output impedance: 100 kΩ
Edge detection: Falling edge, contact closure, or Schmitt-trigger buffer
Preferred switch type: Normally open. For maximum battery life, the event input should be used with its preferred switch type. The logger will work with normally closed switches, but battery life will be compromised.
Open circuit input voltage: Battery voltage; nominally 3.0 V
Maximum input voltage: Battery voltage + 0.3 V
User connection: 24 AWG, 2 leads: white (+), black (-)
Temperature Measurement
Measurement range: -20° to 70°C (-4° to 158°F)
Accuracy: ± 0.53°C from 0° to 50°C (± 0.95°F from 32° to 122°F), see Plot A. A solar radiation shield is required for accurate temperature measurements in sunlight.
Resolution: 0.14°C at 25°C (0.25°F at 77°F), see Plot A
Drift: Less than 0.1°C/year (0.2°F/year)
Response time: Airflow of 2 m/s (4.4 mph): 10 minutes, typical to 90%
Logger
Time accuracy: ± 1 minute per month at 25°C (77°F), see Plot B
Operating range: -20° to 70°C (-4° to 158°F)
Environmental rating: Tested to NEMA 6 and IP67; suitable for deployment outdoors
Drop specification: 1.5 m (5 ft) onto concrete
NIST traceable certification: Available for temperature only at additional charge; temperature range -20° to 70°C (-4° to 158°F)
Battery: CR-2032 3V lithium battery; 1 year typical use
Memory: 64K bytes
Materials: Polypropylene case; stainless steel screws; Buna-N o-ring; PVC cable insulation
Weight: 50 g (1.7 oz.)
Dimensions: 71 x 33 x 23 mm (2.8 x 1.3 x 0.9 inches); 1.8 m (6 ft) cable
The CE Marking identifies this product as complying with the relevant directives in the European Union (EU).
