Deskripsi
Menggabungkan pengukuran ketinggian air berakurasi tinggi dengan kenyamanan out-of-the-box. Data logger ini sangat ideal untuk memantau ketinggian air dan suhu di sumur, aliran, danau dan lahan basah air tawar, serta tekanan barometrik.
Kit ini berisi:
- U20-001-01 HOBO data logger (30′ range)
- U20-001-04 HOBO data logger (13’ range) for Barometric Pressure
- U-DTW-1 HOBO waterproof shuttle with 5 interchangeable couplers
- U20-CASE-1 carrying case
- BHW-PRO-CD HOBOware Pro software.
Seperti HOBO Water Level Loggers lainnya, versi 30-kaki menawarkan nilai luar biasa dan kemudahan penggunaan, tanpa tabung ventilasi atau pengering yang rumit untuk dirawat.
Fitur
- Proteksi petir – tidak ada kabel sinyal panjang, dan elektronik terlindung dalam wadah stainless-steel
- Perangkat lunak HOBOware Pro memberikan konversi yang mudah ke pembacaan ketinggian air yang akurat, tekanan barometrik, dan kepadatan air.
- Pengambilan sampel multi-rate memungkinkan pengambilan sampel lebih cepat seperti ketika pemompaan dimulai atau berhenti.
- Tersedia dalam 4 rentang kedalaman
- Ideal untuk digunakan di sumur, aliran, danau, lahan basah, dan daerah pasang surut
- Desain tanpa ventilasi untuk pemasangan yang mudah dan andal
- Sensor tekanan berbahan keramik yang tahan lama
Spesifikasi
Pressure Sensor
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: < 0.02 kPa (0.003 psi), 0.21 cm (0.007 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), see Plot A
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
