Description
Dengan menggabungkan pengukuran tingkat air dengan akurasi tinggi dengan kenyamanan di luar kotak, kit hemat uang ini mencakup semua yang dibutuhkan untuk segera memulai pembalakan. Ini sangat ideal untuk memantau tingkat air dan suhu di sumur, sungai, danau dan lahan basah air tawar, serta tekanan barometrik.
Kit ini meliputi:
U20-001-04 Data logger HOBO (kisaran 13 ')
U20-001-04 Data logger HOBO (kisaran 13 ') untuk Tekanan Barometrik
U-DTW-1 HOBO kedap air dengan coupler
Tas pembawa U20-CASE-1
Perangkat lunak HOBOware Pro BHW-PRO-CD.
Seperti penebang air tingkat HOBO lainnya, versi 13 kaki menawarkan nilai luar biasa dan kemudahan penggunaan, tanpa tabung ventilasi atau desiccant yang tidak praktis untuk dipelihara.
Di lingkungan apakah kit ini beroperasi?
Kit ini beroperasi di lingkungan luar ruangan dan di bawah air.
Pengukuran apa yang didukung kit ini?
Kit KIT-D-U20-04 mendukung pengukuran berikut: Tekanan Mutlak, Tekanan Barometrik, Suhu dan Tingkat Air
Feature
- Perlindungan petir - tidak ada kabel sinyal yang panjang, dan elektronik terlindung di perumahan stainless steel (lihat gambar lokasi sensor logger Water Level)
- Perangkat lunak HOBOware Pro memberikan konversi mudah ke pembacaan tingkat air yang akurat, kompensasi penuh untuk tekanan barometer (lihat demo), dan kepadatan air.
- Multiple-rate sampling (lihat demo) memungkinkan pengambilan sampel lebih cepat pada saat-saat kritis seperti saat memompa dimulai atau berhenti.
- Tersedia dalam 4 rentang kedalaman
- Ideal untuk digunakan di sumur, sungai, danau, lahan basah dan daerah pasang surut
- Desain no-vent-tube untuk penyebaran yang mudah dipercaya
- Sensor tekanan keramik tahan lama
