What is a soil pH tester and what is its composition and structure?

Through Topyunnong's soil pH meter, we can understand the pH and humidity of the soil. It is very important. The soil pH tester is an instrument specially used to detect acidity and alkalinity. It can be directly inserted into the soil to measure the pH of the soil. It is different from the traditional method of measuring soil pH. The operation is simpler, and direct insertion into the soil for measurement can better reflect the actual situation of the soil.

Soil pH is one of the important basic properties of soil and an indicator of the soil formation and maturation and fertilization process.

In the soil, it participates in many chemical reactions and affects many soil properties. Microbial activity, the synthesis and decomposition of organic matter, the ability of the soil to retain nutrients, and the migration of elements during soil formation are all related to soil pH. Various plants have their own suitable pH range, and their growth will be hindered if it exceeds this range. Therefore, the significance of soil pH measurement is not limited to understanding the soil acidity and alkalinity itself, but also many other soil properties can be judged or inferred based on the pH value.

The soil pH tester is composed of an ammeter with numerical indication, a metal sensor and a function value switching device. That is, the hardware system with the metal sensor as the core, the metal sensor is in contact with the soil, and the current is generated by the oxidation-reduction reaction in the chemical reaction. The magnitude of the current value drives the unit data of the different pH values ​​and humidity values ​​corresponding to the ammeter.
