Merekam ketinggian air dan suhu hingga kedalaman 13 kaki; rentang sempit memberikan akurasi terbaik di perairan dangkal. Tersedia dalam bahan stainless steel untuk sumur dangkal, sungai, danau, dan lahan basah air tawar, serta dalam bahan titanium untuk lahan basah air asin/payau dan wilayah pasang surut.
Perlindungan petir — tanpa kabel sinyal panjang, dan elektronik terlindungi dalam rumah logam.
Perangkat lunak HOBOware Pro menyediakan konversi mudah ke pembacaan tinggi muka air yang akurat, sepenuhnya dikompensasi terhadap tekanan barometrik, suhu, dan densitas air.
Pengambilan sampel multi-kecepatan memungkinkan pengambilan data lebih cepat pada waktu-waktu kritis, seperti saat pompa mulai atau berhenti.
Tersedia dalam empat rentang kedalaman.
Ideal digunakan di sumur, sungai, danau, lahan basah, dan area pasang surut.
Desain tanpa tabung ventilasi untuk pemasangan yang mudah dan andal.
Tersedia dalam versi stainless dan titanium.
Sensor tekanan keramik yang tahan lama.
Termasuk sertifikat kalibrasi 3-titik yang dapat ditelusuri ke NIST.
