HOBO Water Level Titanium direkomendasikan untuk penyebaran air asin untuk pencatatan tingkat air dan suhu di lahan basah dan daerah pasang surut. Data logger ini memiliki akurasi tinggi dengan harga terjangkau dan kemudahan penggunaan HOBO, tanpa tabung ventilasi atau desiccant yang tidak praktis untuk dipelihara.

Di lingkungan manakah logger data ini beroperasi?
Data logger ini beroperasi di lingkungan luar ruangan dan di bawah air.

Pengukuran apa yang dilakukan oleh data logger ini?
Data logger U20-001-03-Ti mendukung pengukuran berikut: Tekanan Mutlak, Tekanan Barometrik, Suhu dan Tingkat Air


 

Pressure and Water Level Measurements

  • Operation Range: 0 to 850 kPa (0 to 123.3 psia); approximately 0 to 76.5 m (0 to 251 ft) of water depth at sea level, or 0 to 79.5 m (0 to 262 ft) of water at 3,000 m (10,000 ft) of altitude
  • Factory Calibrated Range: 69 to 850 kPa (10 to 123.3 psia), 0° to 40°C (32° to 104°F)
  • Burst Pressure: 1200 kPa (174 psia) or 112 m (368 ft) depth

Water Level Accuracy*

  • Typical error: ±0.05% FS, 3.8 cm (0.125 ft) water
  • Maximum error: ±0.1% FS, 7.6 cm (0.25 ft) water
  • Raw Pressure Accuracy** : ±0.3% FS, 2.55 kPa (0.37 psi) maximum error

Resolution  

  • Pressure Response Time (90%)***  
  • Temperature Measurements (All Models)
  • Operation Range: - 20° to 50°C (-4° to 122°F)
  • Accuracy: ±0.44°C from 0° to 50°C (±0.79°F from 32° to 122°F), see Plot A in manual
  • Resolution: 0.10°C at 25°C (0.18°F at 77°F), see Plot A in manual
  • Response Time (90%): 5 minutes in water (typical)
  • Stability (Drift): 0.1°C (0.18°F) per year

Logger

  • Real-time Clock: ± 1 minute per month 0° to 50°C (32° to 122°F)
  • Battery: 2/3 AA, 3.6 Volt lithium, factory-replaceable
  • Battery Life (Typical Use): 5 years with 1 minute or greater logging interval
  • Memory (Non-volatile): 64K bytes memory (approx. 21,700 pressure and temperature samples)
  • Weight: Stainless steel models: approximately 210 g (7.4 oz)
  • Titanium models: approximately 140 g (4.8 oz)
  • Dimensions: 2.46 cm (0.97 inches) diameter, 15 cm (5.9 inches) length; mounting hole 6.3 mm (0.25 inches) diameter
  • 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%.
