Tips: How does a benchtop pH/ion/ORP meter?

A benchtop pH/ion/ORP meter is a laboratory instrument used to measure the acidity (pH), ion concentration, and oxidation-reduction potential (ORP) of a solution. It typically consists of a meter unit and a specialized electrode. The pH electrode measures the hydrogen ion concentration, while ion-selective electrodes detect specific ions based on their selectivity membranes. The ORP electrode measures the electron activity in a solution, providing information about its oxidative or reductive nature. To use the meter, the electrodes are immersed in the sample, and the meter displays readings based on the electrical signals generated. Calibration with standard solutions ensures accuracy. This versatile tool is crucial in various scientific fields, including chemistry, biology, and environmental science, where precise control of solution properties is essential for accurate experimentation and analysis.
