U20-001-04 Data Logger HOBO Nivel Agua y Temperatura




532,00 €

El Data Logger 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.

The HOBO Water Level data logger features high accuracy at a great price and ease-of-use, with no cumbersome vent tubes or desiccants to maintain. This data logger is ideal for recording water levels and temperatures in shallow wells, streams, lakes and freshwater wetlands.

  • Lightning protection - no long signal wires, and electronics are shielded in stainless steel housing for use in freshwater (see the Water Level logger sensor location drawing)
  • El software HOBOware Pro facilita la fácil conversión a lecturas precisas de nivel de agua, totalmente compensadas para las variables de presión barométrica, temperatura, y densidad de agua.
  • Multiple-rate sampling allows faster sampling at critical times such as when pumping starts or stops.
  • Available in 4 depth ranges
  • Ideal for use in wells, streams, lakes, wetlands and tidal areas
  • No-vent-tube design for easy reliable deployment
  • Available in stainless and titanium versions
  • Durable ceramic pressure sensor

The U20-001-02 Data Logger supports the following measurements: Temperature, Barometric Pressure, Water Level

Sensor de Presión
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

Sensor de Temperatura
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

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
