Our 3-in-1 soil moisture meter combines moisture meter, pH acidity and light sensor together, not only help you save both precious time and money, but also let you know plant when to water, and if it has sufficient sunlight or soil pH is good for plant growth. How To Use: Note level and refer to the chart below for you plant's watering needs. MOISTURE METER: Push switch to the left. Insert probe deeply into soil reaching root level. Keep probe close to plant. LIGHT METER: Push switch to the center. Facing the light source, hold the meter next to the plant. Avoid touching sensing element located underneath gauge. SOIL PH METER : Push the switch to the right. Insert probe deeply into soil. A pH reading greater than 7 is alkaline, a reading less than 7 is acidic. Most indoor plants prefer a slightly acidic soil with a pH between 6.5 and 7. Soil that is highly alkaline will cause the leaves to lose their color and stunt the growth of the plant. Acidic soil will cause the leaves to wilt and drop. Important Tips: 1. Do not touch the stone or hard rock soil, if the soil is too hard and dry, easy to damage the probes. 2. Design for testing soil ONLY. 3. After using, need to clean and wipe the probes. 4. Measurement of moisture and pH must be viewed while the unit is in the soil,And the tester must be kept in the soil for 10 minutes or more.
