Measurements & Results |
|
|
SpeckCheck 2 dirt counter measures area, diameter, length, width, equivalent black area, gray level intensity and many other parameters within seconds. Special image processing algorithms ensure accurate detection and measurement even where there are variations in paper brightness and formation. SpeckCheck 2 classifies each particle into a customized size distribution table having up to 50 classes in any progression. Unwanted objects such as shives or fibers can be screened out according to their size, shape or intensity. Size distribution tables are available for standard test methods for visible dirt and you can create others to suit your procedures. SpeckCheck 2 also provides statistical analysis based upon accumulated data including, total count, parts per million, scanned area and count per sq.m. Results may be printed directly in user-formatted tables including a Title and Headings such as Machine number, Grade, Reel etc. SpeckCheck 2 is closely integrated with Microsoft Excel allowing automatic transfer of data to the spreadsheet. This offers complete flexibility regarding tabular and graphical presentation of results. Data may also be saved in other industry standard file formats for transfer to alternative spreadsheets, statistics programs or information management systems for further analysis. |
