Pacific Sensor has been supplying quality corrosion monitoring equipment and services to chemical processing, petroleum, and water treatment industries around the world for over 25 years. Our products include: Corrosion Coupons, Corrosion Racks, Coupon Holders, Weight Loss Analysis for corrosion coupons, Replacement Electrodes, HFRR Test Specimens and Fuel testing.

Our approach is unique and simple: We provide the Coupon with the most consistent surface finish from batch to batch. Consistency provides a confidence that the Coupon is reflecting accurate conditions that exist at the measuring point. Pacific Sensor also offers weighing of the Coupon on an analytical balance to +/- .0001 grams. Computer labels, printouts and archiving are standard when coupons are weighed. Analysis of the exposed coupon is also available with a report. Common alloys are listed and many others are available.

Corrosion Coupon Analysis 


Once weight-loss corrosion coupons are removed from service (exposure period completed), they must be cleaned, weighed, examined, and measured to determine the pitting corrosion rate and the general corrosion rate. Pacific Sensor’s method of measuring internal corrosion is through the use of weight-loss corrosion coupons. Customers are encouraged to secure and ship corrosion coupons immediately after removal from the monitoring location. Upon arrival at the Pacific Sensor lab, the coupons are cataloged and prepared for analysis. The corrosion coupon analysis completed by Pacific Sensor complies with all published industry standards. This includes the recording of weight-loss corrosion coupon before and after analysis has been completed. Reporting is provided on the current analysis, along with any historical corrosion rate to the customer. Pacific Sensor is an ISO 17025 accredited laboratory.
