Deskripsi

Overview

Pencatat data dengan akurasi tinggi dan hemat biaya yang mengukur dan mencatat konduktivitas dan suhu di sungai, danau, dan sumber air tawar lainnya. Direkomendasikan untuk memantau akuifer untuk intrusi air asin dan limpasan jalan dan pertanian, akses terbuka ke sensornya menyederhanakan pembersihan dan pemeliharaan, dan sensor non-kontak meminimalkan kesalahan pengukuran yang terkait dengan penyimpangan. Juga dilengkapi dengan kompensasi penyimpangan berbasis perangkat lunak.

Lapisan titanium pentoksida pada sensor non-kontak mencegahnya bersentuhan dengan air, sehingga mencegah noda atau korosi yang terkait dengan sensor elektroda tradisional. Lapisan sensor ini juga inert, sehingga pengotoran dapat dengan mudah dibersihkan dari sensor.

Features

  • Titanium pentoixed coated non-contact sensor rovides long life and less measurement drift
  • Provides easy access to sensor for cleaning and shedding air bubbles
  • HOBOware Pro software enables start/end-point calibration to compensate for any fouling and provides easy conversion to specific conductance and salinity
  • USB optical interface provides high-speed, reliable data offload in wet environments
  • Compatible with the HOBO Waterproof Shuttle for easy and reliable data retrieval and transport
