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.
What is the relationship between EC and water %? Read More »
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
How does the POGO take its measurements? Read More »
Using the patented and unique Stevens HydraProbe II sensor and its coaxial impedance dielectric reflectometry protocol, POGO measures WFV (aka VWC) and EC to an accuracy of ±1% without any calibration in any soil. Surface heat index and soil temperature are measured with Infrared and a soil temp probe respectively with equal precision. It does

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. Using all three satellite networks including the USA, European and Russian networks, POGO’s GPS precision has improved further since 2022 over
How accurate is the GPS? Read More »
No. The POGO requires no calibration across turf/soil types and remains scientifically accurate and precise across measurements. This was determined from extensive research of POGO’s technology, and research and understanding of turfgrass systems, indicating that no matter what the soil or turf type, no matter what depth of roots exist and no matter if it
Does the POGO need to know what soil type my turf is growing in? Read More »
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.
Does the POGO directly measure salt / salinity? Read More »
No, pH is a measurement in solution. Soil consists of solution, air and particles.
Can pH be measured with the sensor in the soil? Read More »
