The coupon rack simplifies the procedure for establishing a corrosion monitoring program. This unit is pre-assembled and consists of threaded PVC, black iron or stainless steel pipe and fittings.

One to six test sites can be provided so that the multi-metallic systems can be tested. A variable in-line flow regulator can be incorporated into the assembly for critical measurement of water velocities. An optional Y-strainer is available to help maintain water velocity through the flow meter and pipe rack.

The corrosion test rack is designed according to ASTM designation D2688-70 which specifies the monitoring of corrosivity of water in the absence of heat transfer (weight loss methods).
