Luster Leaf® Rapitest® Digital Soil pH Meter
The Rapitest Digital Soil pH Meter is a meter that quickly and accurately determines soil acidity/alkalinity and displays the results in a digital readout. After your soil sample has been analyzed, the enclosed detailed instructions will guide you through your suggested next steps to assure that your soil pH is at the optimal level for whatever you're growing.
- Determines soil pH levels from 3.5 to 9.0
- Probe measures 5.6 inches long
- Can be used in soil with vegetables, fruit, flowers or landscape plants
- Comes with printed instructions and a Plant pH Preference List for over 450 plants (Both documents are also available under the DOCS tab)
- Batteries are needed, and are included (alkaline button cell batteries: A76 / LR44 / AG13 / L1154)
Before Using Your Soil Meter:
For reliable soil pH readings, be sure to polish the probe shaft ONLY (not the tip) and acclimate the probe to the soil before recording a soil pH reading.
- Using the specially supplied pad, lightly shine the probe, carefully avoiding the bullet-shaped tip, to remove any oxides that may have formed on the surface of the metal.
- Wipe the probe clean, always wiping away from the tip and towards the meter body.
Adjusting Soil pH:
Raising and lowering pH is not an exact science and most plants have a reasonably wide pH tolerance, certainly to within 1 pH point. The long list of pH preferences included indicates that while a majority of plants can survive on a pH of around 6.5, some need particularly acid or alkaline soil. Altering pH takes time. Do not expect rapid changes. Work steadily towards giving a plant its ideal conditions. Please see the instructions under the DOCS tab for more information on various soil types.
