Deskripsi

Overview

Menampilkan akurasi tinggi dengan harga terjangkau dan kemudahan penggunaan, tanpa tabung ventilasi atau pengering yang tidak praktis untuk dirawat, logger ini sangat ideal untuk merekam ketinggian dan suhu air hingga kedalaman 100 kaki di sumur dangkal, sungai, danau, lahan basah air tawar (baja tahan karat), lahan basah air asin/payau, dan area pasang surut (titanium).

Features

  • Lightning protection – no long signal wires, and electronics are shielded in a metal housing
  • HOBOware Pro software provides easy conversion to accurate water level reading, fully compensated for barometric pressure, temperature, and water density
  • Multiple-rate sampling allows faster sampling at critical times such as when pumping starts or stops
  • Available in four depth ranges
  • Ideal for use in wells, streams, lakes, wetlands, and tidal areas
  • No-vent-tube design for easy reliable deployment
  • Available in stainless and titanium versions
  • Durable ceramic pressure sensor
  • 3-point NIST-traceable calibration certificate included

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