HOBO pH and Temperature Data Logger

Overview

Logger dengan Fitur Bluetooth
Logger data pH dan suhu yang dirancang untuk pemantauan pH air dalam jangka panjang. Dilengkapi dengan koneksi Bluetooth untuk memudahkan pengaturan awal dan pengunduhan data.

Informasi Penting
Perangkat ini memerlukan aplikasi HOBOconnect serta perangkat seluler atau komputer Windows yang kompatibel. Persyaratan sistem aplikasi dapat dilihat pada bagian bawah halaman perangkat lunak HOBOconnect.

Catatan: Elektroda pH harus selalu disimpan dalam larutan penyimpanan saat tidak digunakan atau saat alat tidak dipasang di lapangan.

Features

  1. Kalibrasi pH terpandu dengan mengikuti petunjuk di layar pada aplikasi HOBOconnect
  2. Casing PVC yang kuat, cocok digunakan di lingkungan air tawar maupun air laut
  3. Pengunduhan data yang cepat dan mudah melalui Bluetooth ke perangkat seluler atau komputer Windows
  4. Sistem pendeteksi air yang membantu memperpanjang umur baterai dan mengurangi kebutuhan perawatan
  5. Elektroda pH tipe potensiometrik dengan bodi plastik, elektrolit gel, dan sambungan kain ganda
  6. Baterai, elektroda pH, serta pelindung tembaga anti-biofouling dapat diganti oleh pengguna
  7. Akurasi pengukuran ±0,10 unit pH pada rentang suhu ±10°C dari suhu saat kalibrasi

Logger

Parameter Spesifikasi
Operating Range -2° to 50°C (28.4° to 122°F) — non-freezing
Depth Rating IP68; waterproof to 40 m (131 ft)
Water Detection Water conductivity level of 100 µS/cm or greater is necessary for reliable detection of water. Deionized water or water below 100 µS/cm may not be detected.
The water conductivity circuit may not reliably detect water that has frozen around the electrodes, i.e. below 0°C (32°F).
Radio Power 1 mW (0 dBm)
Transmission Range Approximately 30.5 m (100 ft) line-of-sight in air
Wireless Data Standard Bluetooth Low Energy (Bluetooth Smart)
Logging Rate 1 second to 18 hours
Logging Modes Fixed interval (normal, statistics) or burst
Memory Modes Wrap when full or stop when full
Start Modes Immediate, push button, date & time, or next interval
Stop Modes When memory is full, push button, date & time, or after a set logging period
Time Accuracy ±1 minute per month 0° to 50°C (32° to 122°F)
Battery Type One AA 1.5 Volt, user-replaceable
Battery Life 1 year typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always On selected in software.
2 years typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Off Water Detect enabled in software.
3 years typical at 25°C (77°F) with logging interval of 1 minute and Bluetooth Always Off selected in software.
Faster logging intervals and statistics sampling intervals, burst logging, remaining connected with the app, excessive downloads, and paging may impact battery life.
pH Electrode Typical Minimum Life 6 months in sample with ionic strength ≥ 100 µS/cm
Memory 152 KB (43,300 measurements, maximum)
Full Memory Download Time Approximately 60 seconds; may take longer the farther the mobile device is from the logger
