Do not touch the stone or hard rock soil, if the soil is too hard and dry, easy to damage the probes. Copper and Aluminum itself does not belong to the hard material, so if the soil is too dry and hard to insert, you can use auxiliary agricultural tools drill hole and then insert. 2. Design for testing soil ONLY. Do not be used to test pure water or other liquid, electrolytic response index will be affected, can only be used to measure the soil. 3. After using, need to clean and wipe the probes. Don't be inserted in the soil for a long time while using. Package Included: 3 in 1 Soil Tester X 1
