A pH meter is an electronic instrument used to measure the acidity or alkalinity of a solution. The pH scale ranges from 0 to 14, with 7 being neutral. Values below 7 indicate an acidic solution, while values above 7 indicate an alkaline solution.
Description
How a pH Meter Works
Electrode Immersion: The glass and reference electrodes are immersed in the solution to be measured.
Ion Exchange: The glass electrode selectively exchanges hydrogen ions with the solution, generating a small electrical potential.
Signal Amplification: The potential difference between the two electrodes is amplified by the amplifier.
pH Calculation: The amplified signal is converted into a pH value using a calibration curve or built-in algorithms.
