The soil tester allows you to measure the soil with scientific methods to measure the light, moisture and ph. of the soil. You will know when to add water, adjust the pH, or change lighting for your garden, flowers, and plants that are indoor and outdoor as well. There is no battery needed to operate the tester all you do is slide the two-prong probe into the ground and flip the switch to one of the readings you want to take.

Press the button on the pen to the MOIST. Values 1-3 indicate that watering is required, 4-7 indicate that the humidity is moderate, 8-10 indicate that it is too wet, and the watering time can be adjusted according to the variety of the plant. Move the button to LIGHT, the measurement range is 0-2000. The larger the value, the stronger the Light intensity. Press the key to the PH, the corresponding table is 8-3.5, the value of 7 is neutral, and the smaller the value is, the more acid the soil needs and the ph. can be adjusted according to what the plant needs
