Do not leave the plant moisture meter in the soil for a long time. Remove it from the soil in time after use.
This soil meter can only be used in soil. Do not use it to test any liquid directly, such as pure water, lemon juice, vinegar, etc. Otherwise, it will damage the probe.
Do not insert the soil meter into very hard soil or touch hard objects, which will easily damage the probe.
If the soil is too loose or too dry, try to add some water and wait 15 minutes before testing.
