LH-PH-S online PH/ORP meter

LH-PH-S online PH/ORP meter

The pH meter is a commonly used instrument equipment, mainly used for precise measurement of the pH value of liquid media, widely used in industries, agriculture, scientific research, environmental protection and other fields.

Measurement principle:

The measurement electrode is immersed in a solution, and H+ions generate a battery voltage between the electrode membrane and the solution. The battery voltage generated by the electrode is proportional to the pH value. The built-in microcomputer circuit of the controller obtains the pH value by measuring the battery voltage.
