Deskripsi
HOBO Water Level Data Logger Starter Kit (100’) Menggabungkan pengukuran ketinggian air dengan akurasi tinggi dengan kenyamanan yang tidak biasa, kit hemat uang ini mencakup semua yang diperlukan untuk memulai pencatatan dengan segera. Alat ini sangat ideal untuk memantau ketinggian dan suhu air di sumur, sungai, danau, dan lahan basah air tawar.
Specification
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
