Deskripsi
Menyediakan rentang pengukuran yang sempit untuk akurasi terbaik, versi ini ideal untuk memantau ketinggian air dan suhu di sumur, aliran, danau, dan lahan basah.
Seperti HOBO Water Level Data Loggers lainnya, versi ini menawarkan nilai luar biasa dan kemudahan penggunaan, tanpa tabung ventilasi atau pengering yang rumit untuk dirawat. Data logger ini sangat ideal untuk merekam level dan suhu air di lingkungan air asin.
Fitur
- Proteksi petir – tidak ada kabel sinyal panjang, dan elektronik terlindung di wadah untuk digunakan dalam air asin
- 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
- Desain tanpa ventilasi untuk pemasangan yang mudah dan andal
- Tersedia dalam versi stainless dan titanium
- Sensor tekanan keramik tahan lama
- Termasuk sertifikat kalibrasi NIST
