HOBO water level data logger ini dapat menampilkan akurasi tinggi dengan harga terjangkau dan kemudahan penggunaan, tanpa tabung ventilasi atau pengering yang rumit untuk dirawat, logger ini sangat ideal untuk merekam ketinggian air dan suhu hingga kedalaman 9 meter (30ft) di sumur dangkal, sungai, danau, lahan basah air tawar (stainless-steel), lahan basah air asin/payau dan daerah pasang surut (titanium).

Fitur

Proteksi petir – tidak ada kabel sinyal panjang, dan elektronik terlindung dalam wadah baja tahan karat untuk digunakan di air tawar (lihat gambar lokasi sensor pencatat Level Air)
Perangkat lunak HOBOware Pro menyediakan konversi yang mudah ke pembacaan ketinggian air yang akurat,
kompensasi penuh untuk suhu tekanan barometrik (lihat demo), dan kerapatan air.
Pengambilan sampel dengan kecepatan ganda (lihat demo) memungkinkan pengambilan sampel yang lebih cepat pada saat-saat kritis seperti saat pemompaan mulai atau berhenti.
Tersedia dalam 4 rentang kedalaman
Ideal untuk digunakan di sumur, sungai, danau, lahan basah dan daerah pasang surut
Desain tabung tanpa ventilasi untuk penyebaran andal yang mudah
Tersedia dalam versi stainless dan titanium
Sensor tekanan keramik tahan lama
Sertifikat kalibrasi yang dapat dilacak NIST 3 titik disertakan
