Purafil - Corrosion Coupon
The Corrosion Coupon by Purafil is designed to diagnose and monitor corrosive air in critical environments over a 30-day period. Utilizing copper and silver metal strips that mimic sensitive electronic components, the coupon is installed in air vents, where it accumulates corrosion if present. After the diagnostic period, the coupon is sent back for laboratory analysis. The results determine the air quality classification based on ISA standards (G1 to GX ratings). Moreover, the Corrosion Coupon+ features a temperature and humidity logger for precise environmental control. Typical results highlight the efficacy of corrosion protection and identify any threats to electronics, allowing for actionable solutions. Purafil, renowned for its industrial expertise and advanced air purification systems, ensures that the environments remain contamination-free, thereby safeguarding electronics, processes, and even historical artifacts for years to come.- Unobtrusive, easy installation and data gathering
- Economical investment for determining air quality
- Scientifically supported, reliable results
- Provides the documentation required for manufacturers’ warranty compliance
- Vital for determining corrective solutions to protect equipment, processes, and artifacts
- Plus, enjoy the benefits of Purafil's digital coupon portal experience
Corrosion Coupons have copper and silver metal strips. These metals represent the sensitive electronic components you rely on when exposed to the air in your environment. Over the course of a 30-day installation period, any corrosive air present will cause build up on the surface of these metal strips. After 30 days, the coupon is sent back to our lab for analysis where our scientists work to determine the air quality classification of the environment. You will receive a detailed report and a results-based solution to help determine next steps.
Additionally, the Corrosion Coupon+ contains a temperature and relative humidity logger for evaluation of controls and limits. Temperature should be maintained consistent with electronic equipment warranty requirements or at the lowest level possible consistent with personal comfort, typically 72°F, 22°C (±2°F, ±1-2°C). Relative Humidity should be less than 50% with close control of deviations, no greater than 6% per hour.
