The Eddington Coupon Rack Kit allows for an economical way to build a corrosion coupon rack.  The kit comes complete with everything you need (including Teflon tape) to assemble your own coupon rack.

The corrosion test rack simplifies the procedure for establishing a corrosion monitoring program. The coupon rack kit consists of ¾” or 1” threaded PVC schedule 40 clear PVC pipe and PVC fittings. The kit is easily assembled via threaded connections and an easy to follow instruction guide. This kit also includes (4) foam covers to minimize exposure to sunlight.

Four test coupon holders are provided so that multi-metallic systems can be tested. An inline 5 or 12 GPM Eddington flow regulator is incorporated into the assembly for
maintaining constant water velocity. A variable in-line flow meter is also available as an option for critical measurement of water velocities. An optional clear 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).
