HOBO MX800 Series Water Data Loggers

 

HOBO Water Data Loggers MX800 bekerja dengan sensor yang dapat diganti-ganti untuk memberikan solusi yang sangat dapat dikonfigurasi untuk memantau konduktivitas/salinitas air, suhu, dan tingkat air. Tersedia dalam model yang mudah dipasang dan sepenuhnya dapat tenggelam (MX801) serta model baca langsung (MX802) untuk pengambilan data yang nyaman tanpa perlu mengeluarkan sensor dari dalam air.

 

 


Feature

  • Kompatibel dengan sensor Konduktivitas, CTD (konduktivitas/suhu/kedalaman), dan DO (oksigen terlarut) yang dapat diganti-ganti (dijual terpisah) - ganti sensor untuk berbagai aplikasi.
  • Dilengkapi dengan Bluetooth, untuk konfigurasi logger yang mudah dan pengambilan data.
  • Mudah dipasang, sepenuhnya dapat tenggelam (MX801) atau langsung dibaca untuk pengambilan data yang nyaman (MX802).
  • Diameter logger kurang dari 2 inci.
  • Pengambilan data lebih cepat melalui Bluetooth 5.0.
  • Fitur pendeteksi air menunjukkan kapan logger berada di luar air (MX801).
  • Termasuk sensor tekanan barometrik (MX802).
  • Hubungkan dua sensor ke satu logger untuk mendapatkan pengukuran seperti DO yang disesuaikan dengan salinitas langsung, tanpa perlu pengolahan data tambahan.
  • Kalibrasi terpandu memastikan data yang akurat. Baterai dapat diganti oleh pengguna.

  The UKCA marking identifies this product as complying with all relevant directives in the UK Declaration of Conformity.
* Water Level Accuracy: With accurate reference water level measurement, known water density, and a stable temperature environment. System Water Level Accuracy equals the sum of the Barometric Water Level Accuracy plus the selected CTD sensor Water Level Accuracy. ** Raw Pressure Accuracy: Absolute pressure sensor accuracy includes all sensor drift, temperature, and hysteresis-induced errors. *** Changes in Temperature: Allow 20 minutes in water to achieve full temperature compensation of the pressure sensor. There can be up to 0.5% of additional error due to rapid temperature changes.
