CSPARKV （28×4×4cm）Plant Moisture Meter, Humidity Hygrometer for Flower Pot, Garden, Farm, Yard, No Batteries Required

Accurate Soil Moisture Detection: The soil hygrometer can tell you whether the soil at the bottom of your pot or garden is dry, moist, or wet, while your eyes and fingers can only determine the moisture level of the soil surface.

Large, Easy-to-Read Dial: The large dial is easy to read and includes three zones with ten scales, making it very simple to understand. Dry - Dry, Moist - Humid, Wet - Wet.

Immediate Moisture Reading: Insert the probe into the soil and, without waiting, the dial will immediately display the moisture level. You can then decide whether your plant needs watering based on the measurement. Do not leave this soil hygrometer in the soil for more than 5 minutes, as the metal tip will gradually corrode.

Less damage: A single probe causes less damage to plant roots compared to double or multiple probes, and when you remove the probe after testing, it will not push out much soil.

Precautions for use: Do not use it to test very hard soil. Do not test water or other liquids. After testing, please wipe the probe to clean it.
