E-Test Sp. z o.o. produces measurement systems for water content, bulk electrical conductivity, temperature and capillary pressure of soil and other porous materials. The TDR devices and probes were designed and developed using the expertise of Laboratory of Dielectric Spectroscopy of the Institute of Agrophysics, Polish Academy of Sciences in Lublin, Poland.
Our devices use fast, accurate and non-destructive time-domain reflectometry technique.
