13-Foot Depth Titanium Water Level Data Logger - HOBO - U20-001-04

13-Foot Depth Titanium Water Level Data Logger - HOBO - U20-001-04


Order Catalog

Description

Menyediakan berbagai pengukuran yang sempit untuk akurasi terbaik, versi ini sangat ideal untuk memantau tingkat air dan suhu di sumur, sungai, danau dan lahan basah.

Seperti penebang data tingkat air HOBO lainnya, versi 13 kaki menawarkan nilai luar biasa dan kemudahan penggunaan, tanpa tabung ventilasi atau desiccant yang tidak praktis untuk dipelihara. Data logger ini sangat ideal untuk mencatat tingkat air dan suhu di lingkungan air garam.

Feature

  • Anti petir - tidak ada kabel sinyal yang panjang, dan elektronik dilisensikan di perumahan titanium untuk digunakan di air asin (lihat gambar sensor lokasi sensorWater)
  • Perangkat lunak HOBOware Pro memberikan konversi mudah ke pembacaan tingkat air yang akurat, kompensasi penuh untuk tekanan barometrik (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 diandalkan
  • Tersedia dalam versi stainless dan titanium
  • Sensor tekanan keramik tahan lama
  • Sertifikat kalibrasi NIST-traceable disertakan

* Water Level Accuracy: With accurate reference water level measurement, known water density, accurate Barometric Compensation Assistant data, and a stable temperature environment.

** Raw Pressure Accuracy: Absolute pressure sensor accuracy includes all sensor drift, temperature, and hysteresis-induced errors.

*** Changes in Temperature: Allow 10 minutes in water to achieve full temperature compensation of the pressure sensor. Maximum error due to rapid thermal changes is approximately 0.5%.
