When measuring soil pH, measure the top clear layer of the solution mixed with a ratio
of 1 part soil to 2.5 parts water.
* Not for commercial use * Calibration with a standard solution (sold separately) is required before use. * If the value after calibration is not stable, replace the electrode part.
