U20-001-03-TI de Titanio para Nivel Agua & Temperatura para Agua Salada (0 a 76 m)

El Registrador de datos HOBO U20 de Nivel del Agua ofrece una alta precisión a un precio asequible. Además, es de fácil uso y no requiere mantenimiento al no ser necesario que se cambien las bolsas desecantes y al estar diseñado sin incómodos tubos de ventilación. Este registrador de datos es ideal para monitorizar el nivel del agua y temperatura en pozos, ríos, lagos, y terrenos pantanosos. Para aplicaciones en agua salada y en áreas de mareas se recomienda el modelo HOBO Water Level Titanium.

Pressure Sensor
Operation range: 0 to 850 kPa (0 to 123.3 psia); approximately 0 to 76.5 m (0 to 251 ft) of water depth at sea level, or 0 to 79.5 m (0 to 262 ft) of water at 3,000 m (10,000 ft) of altitude

Factory calibrated range: 69 to 850 kPa (10 to 123.3 psia), 0° to 40°C (32° to 104°F)

Burst pressure: 1200 kPa (174 psia) or 112 m (368 ft) depth

Water level accuracy*: Typical error - 0.05% FS, 3.8 cm (0.125 ft) water

Maximum error: - 0.1% FS, 7.6 cm (0.25 ft) water

Raw pressure accuracy**: 0.3% FS, 2.55 kPa (0.37 psi) maximum error

Resolution :< 0.085 kPa (0.012 psi), 0.87 cm (0.028 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.
