The PH meter is a scientific instrument used to measure the acidity or alkalinity of a solution.
It is commonly used in various industries such as agriculture, food and beverage, water treatment, and Pharmaceuticals.
The PH meter operates on the principle of measuring the concentration of hydrogen ions (H+) in a solution.
The PH scale ranges from 0 to 14, with 7 being neutral. A PH value below 7 indicates acidity, while a PH value above 7 indicates alkalinity.
The PH meter consists of a PH electrode, which is a glass probe that generates a voltage proportional to the hydrogen ion concentration. This electrode is immersed in the solution being tested and connected to a PH meter device.
The PH meter device measures the voltage generated by the PH electrode and converts it into a PH value.
It typically has a digital display that shows the PH value, allowing users to easily interpret the acidity or alkalinity of the solution.
