Roxar™ Retractable Weight Loss Coupons and Holders
The Roxar™ Retractable Weight Loss Coupons and Holders are used to correlate the corrosion rates on pipe walls by measuring the weight of elements exposed to corrosion over a given period of time.
Effects of pitting, scaling, deposits or bacteria can also be analyzed if required. The retractable coupons are installed on low pressure systems. The corrosion coupons are available in a variety of materials to access corrosion in many types of systems.
