Alat Perekam Data Ketinggian Air Tawar (Kedalaman 100 Kaki) | HOBO 100-Foot Depth Fresh Water Level Data Logger – U20-001-02

Description

HOBO Water Level data logger memiliki akurasi tinggi dengan harga tinggi dan kemudahan penggunaan, tanpa tabung ventilasi atau pengering yang rumit untuk dirawat. Data logger ini sangat ideal untuk merekam tingkat air dan suhu di sumur dangkal, aliran, danau dan lahan basah air tawar.

Fitur

• Proteksi petir – tidak ada kabel sinyal panjang, dan elektronik terlindung di casing berbahan stainless steel untuk digunakan dalam air tawar
• Perangkat lunak HOBOware Pro memberikan konversi yang mudah ke pembacaan ketinggian air yang akurat, tekanan barometrik, dan kepadatan air.
• Pengambilan sampel multi-rate  memungkinkan pengambilan sampel lebih cepat pada waktu-waktu kritis seperti ketika pemompaan dimulai atau berhenti.
• Tersedia dalam 4 rentang kedalaman
• Ideal untuk digunakan di sumur, aliran, danau, lahan basah, dan daerah pasang surut
• Bentuk yang compact tanpa ventilasi untuk pemasangan yang mudah dan andal
• Tersedia dalam versi stainless dan titanium
• Sensor tekanan keramik tahan lama
• Termasuk sertifikat kalibrasi NIST
