Description
Menggabungkan pengukuran tingkat air dengan akurasi tinggi dengan kenyamanan di luar kotak, kit hemat ini mencakup semua yang dibutuhkan untuk segera memulai loggin. Sangat ideal untuk memantau tingkat air dan suhu di sumur, sungai, danau dan lahan basah air tawar.
Kiti ini termasuk:
- U20-001-02 HOBO data logger (100' range)
- BASE-U-4 base station with the required coupler
- BHW-PRO-CD HOBOware Pro software.
Seperti penghitung data tingkat air HOBO lainnya, versi 100 kaki menawarkan nilai luar biasa dan kemudahan penggunaan, tanpa tabung ventilasi atau desiccant yang tidak praktis untuk dipelihara.
Feature
- Anti petir - tidak ada kabel sinyal yang panjang, dan elektronik terlindung di pelindung stainless steel (lihat gambar lokasi sensor logger Water Level)
- Perangkat lunak HOBOware Pro memberikan konversi mudah ke pembacaan tingkat air yang akurat, kompensasi penuh untuk tekanan barometer (lihat demo), suhu, dan kepadatan air (gunakan data tekanan barometrik dari stasiun cuaca terdekat).
- Multiple-rate sampling (lihat demo) memungkinkan pengambilan sampel lebih cepat pada saat-saat kritis seperti saat
- memompa dimulai atau berhenti.
- Tersedia dalam empat rentang kedalaman
- Ideal untuk digunakan di sumur, sungai, danau, lahan basah dan daerah pasang surut
- Desain no-vent-tube untuk penyebaran yang mudah diandalkan
- Sensor tekanan keramik tahan 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.
