Reticle Walton & Beckett

Price: $225.00

Glass eyepiece reticle available in diameters of 19mm or 21mm (select below when ordering). Walton and Beckett reticles are used mainly for counting asbestos dust fibers or glass fibers. Generally the fibers being counted are smaller than 5 microns in size. The circle on the reticle is divided into four by two diametrical lines scaled in units of 5 and 3 microns respectively. These are the critical measurements of fiber lengths and diameters used in asbestos fiber counting. The Walton and Beckett reticle has a series of shapes that have been designed to compare with fibers. You can learn more about asbestos bulk fiber identification microscopes or asbestos fiber counting microscopes here.
