The Silver Digital Detection Imaging (AgDDI) device accurately and robustly rates the corrosion on silver coupons without the need for operating analyses known to be unreliable. The four-step automated VISION algorithm rates the silver corrosion on a scale of 0-4 defined by the ASTM. The AgDDI standardizes the process of silver corrosion testing reliably, ensuring fuels stay within acceptable limits.

In a small and sleek design, silver coupons undergo induced corrosion and then the silver strip is inserted into the AgDDI for determination and rating. The AgDDI works by measuring each pixel on both sides of the silver strip for sulfur-induced blackening and rating the coupon accordingly based on the scale from 0 (no corrosion) to 4 (significant blackening).

This device is fully compliant with ASTM 7691 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

Key Measuring Parameters:
D7691 Corrosion Scale: 0-4

The AgDDI is backed by a comprehensive 1-year warranty, with an option to extend coverage for an additional year upon compliance with the manufacturer’s terms.

The CuDDI standardizes the process of copper strip corrosion testing with unparalleled precision, reliability, and ease of use. The Copper Digital Detection Imaging (CuDDI) device redefines copper corrosion testing by integrating high-resolution camera technology, AI-driven image processing, and algorithms to eliminate manual guesswork and operator bias. CuDDI detects corrosivity levels of products in compliance with ASTM standards and provides a solution for laboratories aiming for efficient and accurate results.

The CuDDI’s innovative and patented design combines optical analysis, artificial intelligence, and a unique lightbox to deliver consistent and precise results, reducing subjective interpretation. A four-step algorithm identifies and rates corrosivity, providing digital documentation and classification. Equipped with Ethernet, USB, and HDMI interfaces, CuDDI integrates seamlessly with laboratory information management systems (LIMS), enabling easy data sharing and analysis. A 10.1” LCD touchscreen for enhanced user interaction and an easy-to-use NFX Handle ensure effortless sample handling and operation.

The CuDDI achieves accurate ratings in under 90 seconds, saving time while maintaining reliability. It generates detailed, zoomable images of both sides of copper strips, with a summary table of results, and optional manual overrides for expert verification. With a compact design of 14” x 12” x 11” (36 x 31 x 28 cm), CuDDI is ideal for laboratory environments.

Applications:
Copper strip corrosion analysis in compliance with ASTM D130, D1838, and other related standards.
Quality control in refineries and terminals to ensure sulfur compounds are within acceptable limits.

Key Measuring Parameters:
Copper corrosion testing; Ratings from 1a to 4C.

The CuDDI is backed by a comprehensive 1-year warranty, with an option to extend coverage for an additional year upon compliance with the manufacturer’s terms.
