Measuring Equipment for Corrosion

Ships sinking, gas pipes exploding, or bridges collapsing are disasters we all want to prevent. That’s why it's crucial to protect and monitor metal structures using cathodic protection. Proper corrosion monitoring could save countless lives and billions of dollars each year by protecting metal structures in electrolyte environments. At Korrosionsgruppen, we contribute to this goal with our On-Off-Sure system, designed to help customers excel in harsh environments that place significant strain on metallic structures.

Corrosion occurs when metal structures in contact with water, soil, or concrete (electrolyte environments) begin to deteriorate. The underlying cause is the metal’s natural tendency to lose energy as it tries to return to its original anode state, resulting in corrosion. To prevent this, cathodic protection is used, either with sacrificial anodes or impressed current systems. For maritime applications, this often involves a combination of good coatings and cathodic protection.

The marine environment is one of the most corrosive on the planet, costing billions in damage each year. On-Off-Sure helps you detect and prevent corrosion before it damages your assets, saving you from costly repairs and equipment loss.

On-Off-Sure is valuable for a wide range of industries, especially in maritime and port environments. On ships, you can measure the potential of areas like hulls, drive shafts, and rudders to ensure proper protection. It also helps detect current leakage. For harbors, measuring corrosion on jetties and other metal structures is made simple, allowing you to compare values with recommended potentials and confirm that your protection system is working as intended. By knowing the potential of your assets, such as ships or port infrastructure, you can prevent corrosion in time, extending the life of your investment while reducing maintenance costs and increasing operational reliability.
