Short Description
The Lutron PH-212 is a professional digital soil pH meter designed for fast and accurate measurement of soil acidity and alkalinity. Equipped with a separate spear-tip pH electrode, it enables direct insertion into soil, compost, and other semi-solid samples for reliable pH analysis. Featuring a wide 0.00 to 14.00 pH measuring range, automatic temperature compensation (ATC), high-resolution LCD display, and microprocessor-controlled circuitry, the PH-212 is ideal for agriculture, horticulture, landscaping, environmental monitoring, research laboratories, and educational institutions.
