Purafil - Corrosion Classification Coupon+
The Corrosion Classification Coupon+ by Purafil is an advanced diagnostic tool designed to detect and measure the presence of corrosive air in critical environments over a 30-day period. This product includes copper and silver metal strips, representing sensitive electronic components, which help identify the level of contamination by corrosive substances such as hydrogen sulfide and sulfur dioxide. Additionally, this coupon features a temperature and relative humidity logger, which records environmental conditions critical for precise analysis. By maintaining consistent temperatures around 72°F (22°C) and relative humidity below 50%, users can ensure optimal conditions for monitoring air quality. Once the exposure period is complete, the coupons are analyzed in Purafil’s ISO 17025:2017 accredited lab, providing a detailed report and tailored solutions based on ISO standards. This innovation is key for industries such as telecommunications, paper manufacturing, refineries, and even historical preservation, offering a scientific and reliable approach to corrosion management.- 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
- Contains a temperature and relative humidity logger for evaluation of controls and limits
- 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.
