When viewing oil filter patches from large machinery, there are two different ranges of magnification that are relevant, as show in the chart below. The filter patch inspection microscopes offered here cover these magnification ranges. Filter patch inspection microscopes are available in two types: binocular and trinocular. Binocular microscope are for viewing purposes only. Trinocular microscopes include a camera to capture images and save or to email images to clients. You can read a bit more about filter patch inspection here.

Common items found in filter patches include plastic, teflon and metal. Based on shape, color and tear patterns in the particles found in the filter patch decisions can be made that will lengthen the life of the machinery. The filter patch microscopes shown below were created for this purpose.
