Kit alat ukur dan perekam ketinggian air HOBO Data Logger KIT-S-U20-02 mencakup semua yang dibutuhkan untuk mengukur dan merekam ketinggian air serta suhu air. Alat ukur ketinggian air ini sangat cocok untuk memantau ketinggian air sungai, danau, dan air tanah.
Kit ini terdiri dari :
- U20-001-01 HOBO data logger (untuk kedalaman hingga 30 meter)
- BASE-U-4 base station untuk mengambil dan transfer data ke komputer/laptop
- BHW-PRO-USB HOBOware Pro Software untuk memproses, melihat, dan mendownload data serta grafik ketinggian air
- Material body berbahan stainless steel untuk proteksi komponen elektronika data logger.
- HOBOware Pro Software memberikan kemudahan konversi ke data ketinggian air yang akurat lewat teknologi Data Assistant. Serta kompnsasi penuh untuk tekanan barometrik, suhu, dan kepadatan air.
- Multiple-rate sampling memungkinkan pengambilan sampel data lebih cepat pada saat – saat tertentu seperti pemompaan dimulai dan berhenti.
- Tersedia empat rentang kedalaman yang berbeda.
- Ideal untuk digunakan di sumur, sungai, danau, lahan basah dan daerah pasang surut
- Desain tabung tanpa ventilasi untuk pemasangan yang andal dan mudah
- Sensor dengan material keramik untuk ketahanan yang lebih lama
Pressure Sensor
Operation range: 0 to 400 kPa (0 to 58 psia); approximately 0 to 30.6 m (0 to 100 ft) of water depth at sea level, or 0 to 33.6 m (0 to 111 ft) of water at 3,000 m (10,000 ft) of altitude
Factory calibrated range: 69 to 400 kPa (10 to 58 psia), 0° to 40°C (32° to 104°F)
Burst pressure: 500 kPa (72.5 psia) or 40.8 m (134 ft) depth
Water level accuracy*: Typical error – 0.05% FS, 1.5 cm (0.05 ft) water
Maximum error: – 0.1% FS, 3 cm (0.1 ft) water
Raw pressure accuracy**: 0.3% FS, 1.20 kPa (0.17 psi) maximum error
Resolution: < 0.04 kPa (0.006 psi), 0.41 cm (0.013 ft) water
Pressure response time 90%: < 1 second
Thermal response time (90%)†: Approximately 10 minutes in water to achieve full temperature compensation of the pressure sensor
* With accurate reference water level measurement and Barometric Compensation Assistant data
** Absolute pressure sensor accuracy includes all pressure drift, temperature, and hysteresis-induced errors
† Maximum error due to rapid thermal changes is approximately 0.5%.
Temperature Sensor
Operation range: -20° to 50°C (-4° to 122°F)
Accuracy: 0.37°C at 20°C (0.67°F at 68°F)
Resolution: 0.1°C at 20°C (0.18°F at 68°F) (10-bit)
Response time (90%): 3.5 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)
Dimensions: 2.46 cm (0.97 inches) diameter, 15 cm (5.9 inches) length; mounting hole 6.3 mm (0.25 inches) diameter
Weight: Approximately 210 g (7.4 oz)
Wetted materials: 316 stainless steel, Viton® o-rings, acetyl cap, ceramic sensor
Shock/drop: Logger is sensitive to shocks. Handle with care and avoid any impact. Always use proper packaging when shipping the logger.
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 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.
Environmental Rating: IP68
