How to direct-test soil pH?
If the soil is dry, add a small amount of distilled or RO water to moisten the soil (do NOT add tap water since it will affect the pH value significantly). Ideally, wait 24 hours before you take a measurement.
Insert the pH connector (the blue one) to the pH socket, and twist it clockwise to lock in; Insert the temperature connector to the temperature socket.
Rinse the probe with distilled water/RO water before inserting it into the soil.
If measuring outside of solution, rockwool or small pots, remove the top 5cm/2inch soil from the surface of the sample area. Insert the probe approximately 4 to 6 inches (10 to 15cm) into the soil samples from various locations (3 to 4), wait for the stable readings before recording (smiley face icon stays on the screen).
Users can press the M+ button to save the stable readings on the meter. Then take the average of the measured data as the representative pH level of the sample area.
Do NOT use extra force to insert the probe. If you feel like the probe can’t be inserted any deeper, stop inserting. The spear tip could break.
Rinse off the soil residue between tests using distilled water for the best results. Use the probe cleaning brush in the case if needed.
