U20-001-01 Registrador HOBO Nivel Agua/Temp




625,00 €

El registrador de datos HOBO del nivel del agua cuenta con una gran precisión a muy buen precio y facilidad -de - uso , sin engorrosos tubos de ventilación o desecantes para mantener. El registrador de datos es perfecto para el registro de los niveles de agua y las temperaturas en pozos poco profundos , arroyos , lagos y humedales de agua dulce . Para las implementaciones de agua salada , agua salobre y humedales : como zonas de marea , ver HOBO U20 nivel de agua de titanio .

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. For saltwater deployments, such as brackish wetlands and tidal areas, see HOBO U20 Water Level Titanium.

  • 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, (ver demo) temperatura, y densidad de agua.
  • Multiple-rate sampling (see demo) 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
  • HOUSING-U2X Protector opcional para entornos extremos
