HOBO MX800 Series Water Data Loggers

Overview

Perangkat data logger nirkabel multiparameter yang sangat serbaguna dan bersifat modular, dirancang untuk mengintegrasikan berbagai sensor (dibeli terpisah) guna mengukur konduktivitas/salinitas air, kedalaman, suhu (CT/CTD), serta oksigen terlarut.

Informasi Penting
Memerlukan aplikasi HOBOconnect dan perangkat seluler yang kompatibel atau komputer Windows. Persyaratan sistem aplikasi dapat dilihat pada bagian bawah halaman perangkat lunak HOBOconnect.

Features

Kompatibel dengan sensor Konduktivitas, CTD (konduktivitas/suhu/kedalaman), dan DO yang dapat dipertukarkan (dijual terpisah) — sensor dapat diganti sesuai kebutuhan aplikasi
Bluetooth, untuk konfigurasi logger dan pengunduhan data yang mudah
Mudah dipasang dan sepenuhnya dapat terendam air (MX801)
Pembacaan langsung untuk pengunduhan data yang praktis (MX802)
Diameter logger kurang dari 2 inci
Pengunduhan data lebih cepat melalui Bluetooth 5.0
Fitur deteksi air yang menunjukkan saat logger berada di luar air (MX801)
Dilengkapi sensor tekanan barometrik (MX802)
Dapat menghubungkan dua sensor ke satu logger untuk memperoleh pengukuran seperti DO yang dikoreksi salinitas secara langsung tanpa perlu pemrosesan lanjutan
Kalibrasi terpandu untuk memastikan data yang akurat
Baterai dapat diganti oleh pengguna
