What is the function of a data logger in cathodic protection surveys?

The function of a data logger in cathodic protection surveys is to record data during surveys. This means that while measurements are being taken across various points in a cathodic protection system, the data logger captures and saves those readings for further analysis. By recording the data, it allows for tracking system performance over time, verifying compliance with design specifications, and assessing the effectiveness of the cathodic protection measures being employed.

Data loggers are essential in ensuring accurate and reliable data collection, enabling technicians to later review performance and make informed decisions regarding system adjustments or maintenance. This capability supports the ongoing monitoring of corrosion rates and the overall effectiveness of cathodic protection systems.
