This multifunctional Soil Moisture Sensor Meter is capable of testing soil moisture, light, and pH values all at once. The switchable modes with a single button make gardening and cultivation more efficient and straightforward. Easy to Use: Simply insert the probes into the soil for instant readings. Assists in fostering your plants to grow healthily and robustly. Material Upgrade for Speed and Accuracy: Our twin probes are crafted from superior quality aluminum and nickel-plated copper materials, offering higher resistance to corrosion compared to the old pure copper. They possess high conductivity and sensitivity, significantly enhancing the speed and precision of soil moisture and pH detection and analysis. This helps in nurturing your plants in the most comfortable environment. Broad Application: This product is ideal for home garden cultivation, rice planting, vegetable planting, forest planting, potted plants, flower planting, greenhouse planting, garden planting, soil testing, and more. It caters to all your soil testing needs. Warm Tips: 1. This Soil Moisture Meter is not designed to test any other liquids. It is strictly for soil testing only. 2. If the soil is excessively dry, the needle won't move. Please water it before testing. 3. Avoid using it to test very hard soil. 4. After each use, remove the probe from the soil and clean it. 5. The soil pH value for most plants is near neutral, hence the test pH needle's range of change will be relatively small.
