Ph meter probes, Nairobi Industrial Area

A pH meter probe is a sensitive device used to measure the hydrogen ion concentration (pH) of a solution. It typically consists of two key components:

Sensing Electrode: This part contains a thin glass membrane that is sensitive to hydrogen ion activity. When immersed in a solution, it generates a voltage proportional to the solution's pH.

Reference Electrode: This component provides a stable reference potential. It usually contains a solution of potassium chloride (KCl) and a porous junction that allows ion exchange.

pH probes are calibrated with standard buffer solutions to ensure accurate measurements. They are commonly used in laboratories, industrial processes, and environmental testing to monitor acidity or alkalinity. Proper care, such as regular calibration, cleaning, and storage in an appropriate solution, is essential for their longevity and performance.
