Moisture meter for INDOOR & OUTDOOR USE: Ideal soil test tool kit for house plants, garden, lawn and farm. ACCURATE: This moisture meter measures the level of wetness between 1 - 10. Level 1 means very dry, and level 10 means very wet. No plants can tolerate the two extremes for long, so it is important to often check on all of your plants.
NOTE: Do not use to test very dry soil. Do not use to test water or other liquid. Designed to only test soil.
