Using the patented and unique HydraProbe II sensor and its capacitance-based coaxial impedance dielectric reflectometry protocol along with Infrared technology and precision instrumentation, the POGO measures water fraction volume (wfv) also known as volumetric water content (vwc), electrical conductivity (EC), Salinity concentration, surface heat index, and soil temperature simultaneously and without calibration, unlike any other sensor. In addition, POGO records on-device precision GPS positioning to pinpoint sample locations specific to your property while allowing for a slew of mapping functions.
