Defender Water Corrision Coupon

Water Corrosion Coupons


Corrosion coupons are a simple yet effective tool for providing a quantitative estimation of corrosion rates occurring in an operating system. They also provide a visual indication of the type of corrosion which may be occurring in the monitored system.


Every Corrosion coupon is stamped with a unique serial number, and every coupon order is supplied with written certification, including: serial number, material, weight and dimensions. All Corrosion coupons are weighed to four (3) decimal places, packaged individually in vapor phase inhibited envelopes and hermetically sealed for a one (1) year shelf life.



Corrosion coupons provide a cost-effective means of monitoring that allows corrosivity measurement in a system in the most accurate manner. This is usually done through the observation of the corrosion rate in mils per year of a coupon exposed in the system. With this, valuable data can be extracted about the life expectancy of materials.
