Corrosion Coupon Rack, used for monitoring corrosion rates, scale formation and erosion of various alloy materials in cooling water systems.
Optional Features for your corrosion monitoring system: Call for quote!
Installation Tips:
Always install the corrosion coupon rack in a horizontal orientation.
Water flow should always enter at the bottom and exit the top.
Water flow should always be passing over the corrosion test sample starting at the holder screw.
Always install your test samples starting with the least noble alloy and finishing with the most noble alloy according to the galvanic corrosion chart.
Example:
A corrosion coupon rack is used to monitor corrosion rates, scaling, and material degradation in water systems by exposing metal test coupons to actual operating conditions. The weight loss and surface condition of the coupons help evaluate system corrosion performance and treatment effectiveness.
They are commonly installed in a side-stream or bypass line of cooling towers, boilers, closed-loop HVAC systems, and industrial water circuits to ensure coupons experience representative water flow and chemistry conditions.
Continuous monitoring helps validate chemical treatment programs, detect early corrosion problems, extend equipment life, and reduce unexpected maintenance or system failure costs.
Accurate readings depend on proper installation, representative flow rate, correct coupon material selection, and controlled exposure time. Variations in flow velocity, temperature, or water chemistry can significantly influence corrosion results.
