Combining high accuracy water level measurements with out-of-the-box convenience, this money-saving kit includes everything needed to start logging right away. It is ideal for monitoring water levels and temperatures in wells, streams, lakes and freshwater wetlands. |
Pressure Sensor 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), 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 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. The CE Marking identifies this product as complying with the relevant directives in the European Union (EU). |
