Description

HOBO MX2501 Data Logger pH dan Suhu dirancang untuk pemantauan jangka panjang pH di muara, danau, sungai, sungai, dan lautan. Memanfaatkan teknologi Bluetooth Low Energy® (BLE), MX2501 pH Logger berkomunikasi secara nirkabel dengan aplikasi HOBOmobile® gratis di perangkat iOS yang membuat pengaturan logger, kalibrasi, dan pemuatan data dengan cepat dan mudah. Proses kalibrasi pH terpandu pada aplikasi HOBOmobile membuat proses rumit yang lebih mudah untuk diikuti. Logger yang terjangkau dan kompak ini secara dramatis memotong waktu dan upaya yang dibutuhkan untuk mengumpulkan data lapangan, sementara juga menawarkan resolusi data yang lebih tinggi.

CATATAN: Elektroda pH harus selalu disimpan dalam penyimpanan jika tidak digunakan.


Feature

  • Kalibrasi pH terpandu mengikuti petunjuk di layar dalam aplikasi HOBOmobile
  • Perumahan PVC yang kokoh untuk ditempatkan di lingkungan air tawar dan air asin
  • Pembongkaran data cepat dan mudah melalui Bluetooth Low Energy (BLE) ke perangkat iOS
  • Sistem deteksi air untuk masa pakai baterai yang lebih lama dan lebih sedikit perawatan
  • Potensiometri pH elektroda dengan badan plastik, elektrolit gel, dan sambungan kain ganda
  • Baterai yang dapat diganti oleh pengguna, elektroda pH, dan pelindung tembaga anti-biofouling
  • Akurasi ± 0,10 unit pH dalam ± 10 ° C suhu saat kalibrasi

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.
