The Corrosion Coupon Test Assembly is used to evaluate the effects of a treated or non-treated water process. The evaluation entails the inspection of test coupons to determine the amount of pitting, corrosion, fouling, or scaling. The test coupons are chosen to simulate the metallurgy found in the water process. The correlation of corrosion and deposit information along with water chemistry data will aid in understanding system conditions and the effects of treatment or lack of treatment on the system.

The PDM-1 Portable Deposition Monitor is designed to effectively simulate the operating conditions of plant heat transfer equipment for evaluation of the effects of a chemical treatment program. The Portable Deposition Monitor provides direct observation of heat transfer surfaces. In conjunction with traditional monitoring tools, such as corrosion coupons and corrosion rate meters, the Portable Deposition Monitor performs a comprehensive diagnostic monitoring of cooling systems for chemical processing, industrial manufacturing, and electric power generation plants. Proper identification and treatment of heat transfer surfaces are essential to prevent decreased heat transfer and ultimately, system failure.
