2、 Function Description
Soil acidity and alkalinity, also known as "soil pH". The general term for soil acidity and alkalinity. Usually used to measure the strength of soil acid-base reactions. Expressed in pH. Neutral soil with a pH between 6.5 and 7.5; Acidic soil below 6.5; Above 7.5 is alkaline soil. The soil acidity and alkalinity sensor is a specially made anti-corrosion electrode made of alloy material - steel needle, which is resistant to acid and alkali corrosion and can be used for real-time online measurement of soil pH in various soil types.
