Description 3-in-1 moisture meter is a multi-functional and professional soil pH moisture, and light testing equipment, allowing you to quickly understand the plant growth environment and make timely adjustments. The soil tester does not require a battery, and the soil can be multi-functionally tested by moving the button. Dual-Probe Design: The soil moisture meter adopts a dual-probe design, which can simultaneously detect soil pH moisture and sunlight data. Soil test kit is upgraded and make the probe is stronger. The sensor component is upgraded. When using our plant soil tester, you can get more sensitive and accurate data. Need to insert the detection probe of the soil moisture meter into the soil, try to keep it at a depth of more than 4 inches. Data is easy to read. Soil moisture meter: 1-10 (1-3 dry, 4-7 neutral, 8-10 wet) pH range: 3.5-8 (3.5-6.5 acid, 7 neutral, 7-8 alkaline) solar light range; 0 -2000lux (0-200 low, 200-500 low, 500-1000 neutral, 1000-2000 high). The soil moisture meter should not be inserted into the soil for a long time, which may damage the oxidation probe. Do not use the probe to touch hard objects forcibly, which will damage the moisture meter probe and cause inaccurate data. Do not use the soil test kit to directly test water or other liquids.
