Half Cell Potentiometer

About Half Cell Potentiometer

The Half Cell Potentiometer is a precision instrument designed to evaluate the corrosion potential of steel reinforcement in concrete structures. Manufactured using high-quality components, it provides accurate and reliable measurement of electrical potential differences, enabling early detection of corrosion and structural deterioration.

The instrument operates by connecting a reference electrode (commonly copper/copper sulfate) to the concrete surface and measuring the voltage difference with embedded reinforcement. The obtained readings indicate the likelihood of corrosion activity, making it an essential tool for structural health monitoring.

It features a digital display with high resolution, allowing easy reading of millivolt values. The unit is portable, battery-operated, and suitable for both laboratory and on-site applications such as bridges, buildings, dams, and industrial structures.
