HOBO Water Level (30 ft) Data Logger - U20L-01



Order Catalog

Description

HOBO U20L-01 adalah data logger dengan biaya yang rendah bagi keperluan tingkat penelitian untuk mengukur kadar air dan suhu di berbagai lingkungan bawah laut. Memiliki akurasi pengukuran 0,1%, perumahan polypropylene untuk digunakan di air tawar dan garam, dan desain non-vented untuk pemasangan yang mudah dan tanpa kerumitan.


Feature

  • Desain non-vented mandiri memungkinkan penyebaran yang mudah ideal untuk digunakan di lingkungan air tawar dan air asin, termasuk sumur, sungai, danau, lahan basah, dan daerah pasang surut
  • Kedalaman sampai 30 kaki
  • Sensor tekanan keramik tahan lama menahan pembekuan
  • Software HOBOware Pro memberikan konversi mudah ke pembacaan tingkat air yang akurat, kompensasi penuh untuk tekanan barometrik (lihat demo), suhu, dan kepadatan air

CE Compliant The CE Marking identifies this product as complying with all relevant directives in the European Union (EU).

 

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