In many cases, as moisture goes up, salts in solution go up and therefore EC goes up. But this is not always the case and EC-to-moisture ratios change from many affecting variables in turf dynamics.
Category: Measurement Process
Using a precisely-tuned and unique process focusing on dielectric permittivity of moisture and EC, making it the only commercially-available research-grade sensor requiring no calibration across turf/soil types. Surface temperature is measured using a thermistor in the plate that rests on the turf (POGO Pro) or via an infrared sensor (POGO Pro+). Soil temperature is measured …
Using the patented and unique Stevens HydraProbe sensor and its coaxial impedance dielectric reflectometry protocol, the POGO measures WFV and EC to an accuracy of ±1% without any calibration in any soil. Visit soilsensor.com to learn more about various measurement methods.
Smartphone GPS receivers are rated at 4.6 m (16 ft) accuracy. However, the integrated GPS in the POGO Pro+ and POGO Pro has sub-meter accuracy when receiving signals from 9 or more GPS satellites.
No. The POGO requires no calibration across turf/soil types and remains scientifically accurate and precise across measurements.
It does not directly measure “Salt” (NaCl). But it does measure salinity activity by measuring EC. All salts (+ and – ions) in solution add to EC.
No, pH is a measurement in solution. Soil consists of solution, air and particles.
