OverView

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.


Pressure and Water Level Measurements

  • Operation Range 0 to 145 kPa (0 to 21 psia); approximately 0 to 4 m (0 to 13 ft) of water depth at sea level, or 0 to 7 m (0 to 23 ft) of water at 3,000 m (10,000 ft) of altitude
  • Factory Calibrated Range 69 to 145 kPa (10 to 21 psia), 0° to 40°C (32° to 104°F)
  • Burst Pressure 310 kPa (45 psia) or 18 m (60 ft) depth
  • Water Level Accuracy* Typical error: ±0.075% FS, 0.3 cm (0.01 ft) water
  • Maximum error: ±0.15% FS, 0.6 cm (0.02 ft) water
  • Raw Pressure Accuracy** ±0.3% FS, 0.43 kPa (0.063 psi) maximum error

  • Wetted Materials Titanium, Viton® o-rings, acetyl cap, ceramic sensor
  • Logging Interval Fixed-rate or multiple logging intervals, with up to 8 user-defined logging intervals and durations; logging intervals from 1 second to 18 hours. Refer to the HOBOware software manual.
  • Launch Modes Immediate start and delayed start
  • Offload Modes Offload while logging; stop and offload
  • Battery Indication Battery voltage can be viewed in status screen and optionally logged in datafile. Low battery indication in datafile.
  • 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 10 minutes in water to achieve full temperature compensation of the pressure sensor. Maximum error due to rapid thermal changes is approximately 0.5%.
