Data Logger ketinggian air HOBO memiliki akurasi tinggi dengan harga terjangkau dan kemudahan penggunaan, tanpa tabung ventilasi atau pengering yang rumit untuk dirawat. Pencatat data ini sangat ideal untuk merekam ketinggian air dan suhu di sumur dangkal, sungai, danau, dan lahan basah air tawar.
Alat perekam ketinggian air dan suhu hingga kedalaman 250 kaki tanpa tabung ventilasi atau bahan pengering yang merepotkan untuk maintenance. Tersedia dalam bahan stainless steel untuk sumur dangkal, sungai, dan rawa air tawar dan dalam bahan titanium untuk rawa air asin/keruh dan daerah pasang surut.
