Description
Menggabungkan pengukuran tingkat air dengan akurasi tinggi dengan kenyamanan luar biasa, kit hemat uang ini mencakup semua yang dibutuhkan untuk segera memulai logging. Sangat ideal untuk memantau tingkat air dan suhu di sumur, sungai, danau dan lahan basah air tawar.
Kit ini termasuk :
- U20-001-04 HOBO data logger (13' range)
- BASE-U-4 base station with the required coupler
- BHW-PRO-CD HOBOware Pro software.
Sama seperti Hobo Water Levels Data Logger lainnya, versi 13-kaki ini menawarkan nilai luar biasa dan kemudahan penggunaan, tanpa tabung ventilasi atau desiccant yang tidak praktis untuk dipelihara.
Feature
- Anti air - tidak ada kabel sinyal yang panjang, dan elektronik terlindung di casing 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 145 kPa (0 to 21 psia); approximately 0 to 4 m (0 to 13 ft) of water depth at sea level, or 0 to 7 m (0 to 23 ft) of water at 3,000 m (10,000 ft) of altitude
Factory calibrated range: 69 to 145 kPa (10 to 21 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 - 0.075% FS, 0.3 cm (0.01 ft) water
Maximum error: - 0.15% FS, 0.6 cm (0.02 ft) water
Raw pressure accuracy:** 0.3% FS, 0.43 kPa (0.063 psi) maximum error
Resolution: < 0.014 kPa (0.002 psi), 0.14 cm (0.005 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

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), see Plot A
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
