XLUX Soil Moisture Meter, Plant Water Monitor, Hygrometer Sensor for Gardening, Farming, Indoor and Outdoor Plants, No Batteries Required

Accurate Soil Moisture Detection：The XLUX Soil Moisture Meter can tell you if the soil deep inside your pot or garden is dry, moist or wet; whereas your eyes and fingers can only resolve the moisture level of the soil surface.
Easy-to-Read Large Dial: The large dial is easy to read and includes three zones with ten scales, making it very straightforward to remember.
Immediate Moisture Reading: Insert the probe into the soil, and without waiting, the dial will right away display the moisture level. You’ll be able to then come to a decision whether your plant needs watering based on the measurement. Do not leave this moisture meter in the soil for more than 5 minutes, as the metal tip will regularly corrode.
Less Damage: A single probe causes less damage to plant roots in comparison to double or more than one probes, and when you put off the probe after testing, it may not bring out much soil.
Usage Precautions: Do not use it to test very hard soil. Do not test water or other liquids. After testing, please wipe the probe clean.
