Registrador de Datos económico de bajo coste para Nivel de Agua

The HOBO U20L-01 is a low-cost, research-grade data logger for continuously measuring water level and temperature in a wide range of underwater environments. It features 0.1% measurement accuracy, a polypropylene housing for use in both fresh and salt water, and a non-vented design for convenient and hassle-free deployment.

  • Self-contained non-vented design enables easy deployment
  • Ideal for use in both fresh and saltwater environments, including wells, streams, lakes, wetlands, and tidal areas 
  • Depths up to 30 feet (0-9 m)
  • Durable ceramic pressure sensor withstands freezing
  • 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.

Entorno:
El Registrador de Datos U20L-01 Data es para uso en entornos de Intemperie y Bajo Agua

Medidas:
El Registrador de Datos U20L-01 soporta las siguientes medidas: Temperatura, Presión Barométrica, Nivel de agua

IMPORTANTE: HOBO data loggers require HOBOware software (USB interface cable included w/CD purchase) and a communications device. Ver Software/Accesorios.
