The pH electrode has really superior interior resistance, making the voltage transform with pH tricky to measure. The input impedance with the pH meter and leakage resistances are thus important factors. The pH meter is largely a high impedance amplifier that properly measures the minute electrode voltages and displays the outcome immediately in pH

Especially for swimming pools and spas, it is necessary to consistently measure and regulate the pH value with the water. For community pools This really is even mandatory. Primarily by using a very low pH value of swimming water this can cause corrosion of the steel sections from the pool, but a also small pH value also can trigger the bound chlor
