QS Fibre Releases QualScan Image Analysis Software

Posted 10/7/2017

QS Fibre has just released its new image analysis software. The application runs in Windows 7-10 and all you need in addition to your PC is a flat-bed scanner. Install the freeware software and you're good to go. There is a single platform licensing USB hardware dongle that is available for purchase that will unlock QualScan's full functionality. But the freeware without the dongle will perform a particle count and provide a total area and average area reading. The scanned area of interest is a 205 mm diameter circular region drawn from the reference corner of the scanner bed. With the purchased dongle in place, QualScan provides more complete measurements including perimeter, luminosity, and circularity. It also stores results in a retrievable and exportable database.
