HOBO Water Level Titanium direkomendasikan untuk penyebaran air asin untuk pencatatan kadar 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 pemeliharaan.

 


Pressure and Water Level Measurements

  • Operation Range: 0 to 207 kPa (0 to 30 psia); approximately 0 to 9 m (0 to 30 ft) of water depth at sea level, or 0 to 12 m (0 to 40 ft) of water at 3,000 m (10,000 ft) of altitude
  • Factory Calibrated Range: 69 to 207 kPa (10 to 30 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: ±0.05% FS, 0.5 cm (0.015 ft) water
  • Maximum error: ±0.1% FS, 1.0 cm (0.03 ft) water
  • Raw Pressure Accuracy**: ±0.3% FS, 0.62 kPa (0.09 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%.

  • Anti petir - tidak ada kabel sinyal yang panjang, dan elektronik dilisensikan di casing/pelindung 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.
  • Juga tersedia dalam kisaran kedalaman sempit (U20-001-04-Ti)
  • 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 3-point disertakan
