Accurate Electrochemical Measurement of Metal Corrosion Activity

Corrosion Rate Test using Linear Polarisation Resistance (LPR) is an advanced electrochemical method used to quantify the instantaneous rate of corrosion in metallic materials—including steel reinforcement in concrete, pipelines, tanks, and structural metals. This test helps engineers, consultants, and asset owners assess corrosion severity, remaining service life, and maintenance needs in a scientifically validated, non-destructive way.

Why Corrosion RateMatters.

Quantifies Active Corrosion

By measuring polarisation resistance (Rp) and converting it to a corrosion rate, engineers can determine whether corrosion is active and how fast material loss is occurring.

Supports Structural Durability Evaluation

Corrosion significantly weakens metallic components over time. Reliable corrosion rate data help evaluate structural durability, integrity, and the effectiveness of protective measures such as coatings or inhibitors.

Enables Informed Maintenance Planning

Accurate corrosion rate measurements support service life modeling, maintenance scheduling, and lifecycle cost analysis for bridges, buildings, marine structures, and industrial assets.

Verifies Protection & Mitigation Strategies

Post-treatment testing (e.g., after coatings or corrosion inhibitors) confirms whether protective solutions are effective in slowing corrosion progression.
