Corrosion Coupons / Probes

Corrosion Coupons & Probes are available

The corrosion coupon is one of the most useful tools for monitoring corrosion. Coupons are of a predetermined shape, size and surface area, and are typically made of a metal of similar chemical composition to that of the process equipment. Their weight and surface preparation is recorded before insertion into the process stream, and they are then re-weighed and visually analyzed after a set exposure period.

The ER coupon technique can be applied for corrosion rate assessment as an alternative to the weight loss coupon. Unlike the weight loss coupon, the ER coupon technique does not require excavation and weighing procedures since a mass loss is assessed by electronic means.
