HOBO U20L

Overview

Seri data logger untuk memantau level air dan suhu air di sumur, sungai, danau, lahan basah, dan area pasang surut. Tersedia dalam tiga rentang kedalaman: 4 m (13 ft), 9 m (30 ft), dan 30 m (100 ft), tanpa pipa ventilasi yang perlu dirawat.

Fitur Utama

  • Tiga pilihan rentang kedalaman: 4 m (U20L-04), 9 m (U20L-01), dan 30 m (U20L-02)
  • Sensor tekanan keramik dalam housing polypropylene, cocok untuk air tawar maupun air asin
  • Desain tanpa pipa ventilasi: tidak ada tabung atau desiccant yang perlu dirawat
  • Mencatat tekanan absolut dan suhu, lalu dikonversi menjadi level air di software
  • Baterai lithium 2/3 AA dengan umur tipikal 5 tahun pada interval pencatatan 1 menit atau lebih
  • Pengaturan dan pengambilan data memakai HOBO Waterproof Shuttle (U-DTW-1) atau Optic USB Base Station (BASE-U-4) dengan coupler, dan software HOBOware
