System supports EN 10247 European standard for determining the content of non-metallic inclusions in steel, as well as previous standards including, DIN 50602, ASTM E 45, ISO 4967; JIS G 0555
The non-metallic inclusions (NMI) system is based on the AxioImager.Z1m upright microscope or the Axio Observer.Z1m inverted microscope to provide the optimal conditions for reliable and convenient measurements of non-metallic inclusions in steel.
The NMI system can be tailored for further image analysis applications such as grain size analysis and particle analysis, and ensures reliable, reproducible and convenient measurements.
All the components of the microscope, ranging from the camera to the motorized stage, are controlled by Zeiss AxioVision software for full functionality.
With the new NMI system, quality is determined through an automated process performed by repeatable mathematical calculations - a dramatic improvement over the prior methods, which involved visual comparison of a sample to a reference chart image.
What's more, the NMI system allows automatic objective analysis on up to six samples at a time using batch mode, and can output the results of a batch measurement either individually or combined.
The integrated NMI software offers the option of performing measurements on a large MosaiX image, a composite of many individual tile images.
This feature addresses the inaccurate classifications that occur when inclusions cut off at the image edge are not recorded in their entirety during independent individual tile analysis.
With the NMI system, sample evaluation is not only more accurate, but it is much faster and easier than the previous manual and visual evaluation methods, especially if the sample is measured against multiple standards.
