Description
Lusterleaf Rapitest 1845 Digital soil pH meter
Plants need the right acidity (pH) of the soil to properly absorb the nutrients present in the soil. This meter directly shows the pH value of the soil in the form of a digital number. Plants have different ideal pH values, so it is important to know whether the pH value of the soil deviates from this in order to adjust (decrease or increase) the pH value of the soil. In the instructions for use a list with the ideal pH value of more than 400 plants is included. You can also easily look up the ideal pH value of plants on the internet.
At the beginning of each pH measurement, you should thoroughly clean the probe with the supplied scouring pad or a green kitchen sponge. Make sure the probe is always clean and shiny! Always clean the probe from the tip upwards.
Make sure the soil is well wet before measuring!
For outdoor measurements only, remove a 5cm layer of soil first. Then loosen the soil below to a depth of 12 cm and remove all obstacles such as stones, twigs and other organic matter. If you do not measure in free ground, this can affect the measurement result. For measuring pot and house plants, you can measure directly in the (potting) soil without the preparations as described above. Make sure the soil is well wet, preferably by using distilled water.
Now press the button to activate the meter and push the probe vertically into the wet soil. If the meter does not slide into the ground easily, do not force it but choose another spot in the ground. Now rotate the gauge clockwise and counterclockwise between your fingers a number of times to ensure that the wet soil is evenly distributed over the surface of the probe. Now wait 1 minute before writing down the measurement result.
If the result is a pH value of 7,0 or higher, pull the pen out of the soil and wipe the pen well. Then make the pen shiny again with the scouring pad. Now push the pin into the ground again in a different place. Now turn the meter clockwise and counterclockwise between your fingers again a few times to ensure that the wet soil is evenly distributed over the surface of the probe. Now wait 30 sec. before recording the measurement result.
To obtain an even better result, you can also follow the following measuring procedure:
1. Take a sample from the ground and remove all obstacles such as twigs, stones etc..
2. Use your fingers to crush the soil into a loose and compact mass without obstacles and lumps.
3. Now fill 2 cups with the prepared soil.
4. Fill a clean plastic container with 2 cups of distilled water and add the 2 cups of soil.
5. Make sure that the soil and water mix well and make a compact mass by pressing the soil well. Now remove the excess water from the container.
6. Now carry out the measurement as described above.
