Description
Data Logger Suhu & pH HOBO MX2501 dirancang untuk pemantauan pH jangka panjang 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 diperlukan untuk mengumpulkan data lapangan, sementara juga menawarkan data resolusi yang lebih tinggi.
CATATAN: Elektroda pH harus selalu disimpan dalam solusi penyimpanan jika tidak digunakan.

| 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. |
