This 3-in-1 soil test kit provides comprehensive soil analysis by testing moisture, pH and fertility, outperforming single-function meters to help you precisely control plant watering and fertilization. Its high-quality single-probe design causes minimal damage to plant roots when inserted into soil, ensuring accurate and reliable measurement results each time you use it. It features a large, easy-to-read dial and a compact, portable build that works seamlessly for indoor houseplants, outdoor gardens, farms, lawns and various other soil and plant analysis needs. No batteries are required for operation; simply switch the function button, insert the probe at least 4 in. deep into soil, and receive test results in just a few seconds. Remember to wipe the probe clean after each use, and only use this tool for soil testing rather than water or other non-soil liquids.
