HOBO 250-Foot Depth Water Level Data Logger

Overview

Menawarkan akurasi tinggi dengan harga terjangkau dan kemudahan penggunaan, tanpa tabung ventilasi atau bahan pengering yang merepotkan untuk dirawat, alat pencatat ini ideal untuk merekam ketinggian air dan suhu hingga kedalaman 250 kaki di sumur dangkal, sungai, danau, lahan basah air tawar (stainless steel), lahan basah air asin/payau, dan daerah pasang surut (titanium).

Fitur

  • Perlindungan terhadap petir – tidak ada kabel sinyal yang panjang, dan komponen elektronik terlindungi dalam wadah logam.
  • Perangkat lunak HOBOware Pro menyediakan konversi mudah ke pembacaan ketinggian air yang akurat, sepenuhnya dikompensasi untuk tekanan barometrik, suhu, dan kepadatan air.
  • Pengambilan sampel dengan berbagai laju memungkinkan pengambilan sampel yang lebih cepat pada saat-saat kritis seperti ketika pemompaan dimulai atau berhenti.
  • Tersedia dalam empat rentang kedalaman.
  • Ideal untuk digunakan di sumur, sungai, danau, lahan basah, dan daerah pasang surut.
  • Desain tanpa tabung ventilasi untuk pemasangan yang mudah dan andal.
  • Tersedia dalam versi stainless steel dan titanium.
  • Sensor tekanan keramik tahan lama
  • Sertifikat kalibrasi 3 titik yang dapat ditelusuri ke NIST disertakan.
