Rated pixel by pixel.
Introducing the AgDDI: automated sulfur corrosion analysis on silver strips
The Silver Digital Detection Imaging (AgDDI) device accurately and robustly rates the corrosion on silver coupons, without relying on manual visual assessments known to be unreliable. The four-step automated VISION algorithm rates silver corrosion on the 0 to 4 scale defined by ASTM. The AgDDI standardizes the process of silver corrosion testing reliably, ensuring fuels stay within acceptable limits.
Automated optical analysis
Both sides.
Every pixel measured.
Four-step VISION algorithm. No operator bias.
In a small and sleek design, silver coupons undergo induced corrosion, and the silver strip is then inserted into the AgDDI for determination and rating. The AgDDI measures each pixel on both sides of the silver strip for sulfur-induced blackening and rates the coupon accordingly, on a scale from 0 (no corrosion) to 4 (significant blackening).
Built for standardized testing.
This device is fully compliant with ASTM D7691, making it the ideal unit for R&D, QC, and many more applications.
Applications of the AgDDI include
- Silver corrosion by gasoline fuels
- Sulfur-induced blackening on silver strips
