Corrosion Coupon

Application

Passive method for measuring the corrosivity of critical environments using copper and silver coupons.

Application areas

Deltrian corrosion coupons are designed for the passive measurement of ambient air corrosivity in critical environments. They allow the detection of corrosive gases that may damage electronic equipment and control systems.

Each coupon consists of a support plate incorporating two high-purity metallic strips of copper and silver, packaged in a sealed container to prevent contamination prior to installation.
