HOBO U20L-04

Overview

Data logger level air dan suhu air untuk kedalaman hingga 4 m (13 ft). Rentang yang sempit memberi resolusi halus untuk perairan dangkal seperti sumur dangkal, sungai kecil, dan lahan basah.

Fitur Utama

  • Rentang kedalaman 0–4 m (13 ft) pada permukaan laut
  • 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
