Soil/Liquid pH Meter
Testing Soil
1. Prepare the soil sample for test: Take away all the stones, clod, glass, etc.
2. Tenderly clean the probes with an abrasive soft paper and dry cloth or a toilet paper. Make sure that the probes are clean and dry, then insert the probes into the soil to be tested. If the soil is too dry, wet it.
Testing Liquid
Attention: The tester is not submarine. Only the probes can be inserted into liquid.
1. Prepare the liquid sample in a glass or glass jar.
2. Make sure that the probes are clean and dry.
3. Insert the probes into the liquid.
4. Read the PH value on the bottom scale after 60 seconds.
Note: The insertion depth of the probes should be between 3cm and 15cm. For better measurement accuracy, it is recommended to insert the probes into the soil/liquid to the depth of about 15cm ( about 3/4 of probe length ) if the soil/liquid is thick/deep enough.
