Each plant has an optimal pH range, and regular pH measurements with a soil acid meter are essential to promoting optimal plant growth. Sprinkle water on the soil, mix well, let it sit for about 20 minutes, then insert it and you can measure the soil acidity in about 1 minute. You can check the appropriate moisture status when measuring soil acidity (pH) by flipping a switch. Since the probe is 77mm long, it is possible to measure the condition of the area where plants have established their roots. When the electrode touches the soil, electricity is generated and the needle moves, so no batteries are required. The meter is located in a position that is easy to read when inserted vertically into the soil.
