V4L FilterPatchScan is a complete hardware and software package for the automatic sizing and counting of particles in filter patch images.

The particle counts are then used to produce ISO 4406 cleanliness codes and reports in HTML format automatically. The system can image particles down to 4 microns in size and does not require a microscope. Sample imaging, processing and report generation takes a matter of minutes.

Whether you are working on the road or working in a specialist laboratory FilterPatchScan can be configured to meet your needs with various output and portablility options.


Easy handling.

Unlike other particle counting products, V4L FilterPatchScan allows the operator to see the many different particle types present in oil samples from a range of applications.

Particle images are presented size sorted, labelled and groupe into the ISO 4406 size categories.

Individual particles may be selected for inclusion in the report by simply clicking and adding comments – no time consuming cutting and pasting of the image necessary!
