[EN]: Time Domain Reflectometry (TDR) is a widely used technique that allows real time estimation of soil volumetric water content (θ), and bulk electrical conductivity (σa). This work presents an enhanced release of TDR-Lab, software which controls instrumentation for measurements of θ and σa. TDR-Lab 2.0 supports three different TDR equipments and can be connected to a multiplexing system (SDMX50, Campbell Sci). Graphical or numerical methods can be used for the estimation of θ and σa. Additional features to carry out water-surface-level measurements such as matric potential and soil solution electrical conductivity are also available. A little and a full release, for field and laboratory applications have been developed. The light version works with XML-files instead of the SQL database engine of the extended TDRLab. A robust import/export graphical user interface facilitates transferring projects between the centralized SQL database and XML files.
[ES]: La técnica de Reflectometría de Dominio Temporal (TDR) permite estimar la humedad (θ) y la conductividad eléctrica aparente del suelo (σa). Esta comunicación presenta una nueva versión del programa TDR-Lab para la medida de θ y σa. El TDR-Lab 2.0 es compatible con tres ecómetros TDR diferentes y puede conectarse a multiplexores SDMX50 (Campbell Sci). Puede estimar θ y σa por métodos gráficos y numéricos y incluye nuevas aplicaciones para la medida de niveles de agua, potencial mátrico o conductividad eléctrica de la solución del suelo. Está disponible en una versión ligera que trabaja con ficheros XML y una versión completa que centraliza los datos en una base SQL. Una robusta interface de importación-exportación de datos permite comunicar ambas versiones.
