IP66 automatic digital ph meter for water treatment

The pH meter is a device used to control the pH of a liquid. It can adjust the pH of the liquid by adding acid or alkali to achieve the desired pH value. The dosing function of the pH controller is realized based on the principle of feedback control, that is, according to the difference between the pH value of the liquid detected by the sensor and the set value, the dosing amount is adjusted by controlling the opening and closing of the dosing valve, so that the liquid The pH value reaches the set value. The advantage of the pH meter is that it can realize automatic control without manual intervention, which greatly improves production efficiency and product quality. In addition, the digital pH meter can also avoid the occurrence of over-dosing or under-dosing, thus ensuring the stability and reliability of the production process. Features…
