Please NOTE: This soil tester cannot be applied to test pH value of other liquid. If the soil is too dry, the indicator will not move, and water before testing 3-IN-1 FUNCTION: Test soil moisture, pH value and sunlight level of the plant with our soil meter, helps you specialize in grasping when you need to water your plant RELIABLE ACCURATE: Dual needle detection technology highly improves the speed and accuracy of detecting and analyzing soil moisture and pH acidity EASY TO USE: No batteries required, just insert the probe into the soil about 2-4 inches, toggle switch to test moisture, pH, sunlight you want to measure INDOOR OUTDOOR USE: Design to be lightweight and portable, easy to carry for outdoor, ideal soil testing tool kit for home plants, garden, lawn and farm. 3-in-1 Soil Moisture Meter is designed to better know the condition of your plant, detect soil moisture, help you know the pH value of the soil, determine if plants are getting enough sunlight to keep plants grow healthier! Scientific data monitoring help you control every detail and track every change on your plants. Keep your plants healthy through scientific data monitoring Special Reminder: 1. The pH function of this soil tester cannot be applied to the testing pH value of other liquid. 2. Since the soil is most often in/close to neutral state (with a pH value of 7), it is very likely that you will find the needle in the display window remains still (because the default pH value is set between 7 and 8) when you use it to test the soil pH value. Customers are sometimes misled by this appearance and therefore consider the tester as a defective unit by mistake. How to Use: Step 1: Switch to the moisture/pH/light position according to demand. Step 2: Insert the probe into the soil about 2-4 inches. Step 3: Check the moisture/pH/light level in the dial after 10 minutes. Step 4: Remove the probe from the soil and clean it after each use. Please Note: 1. Do not force it into very hard soil or touch hard objects as it will be easy to damage the probe. 2. Do not use it to test pure water or other liquids. It can only be used to measure soil. 3. Do not leave the meter in the soil for a long time. 4. Please wipe and clean the probe after each use. 5. If the soil is too dry, the indicator does not move and water it before testing.
