Stop guessing which mesh count is on your frame. Mesh Determiner is easy to read both U.S. and metric mesh numbers of monofilament and multifilament fabric, either from roll or stretched on frame. Two different scales are used for monofilament meshes, one for USA mesh counts from 100 to 240, and metric counts from 40 to 95; the other for those USA counts from 200 to 480, and metric counts from 78 to 190. Multifilament chart determines mesh counts from 6XX to 25XX, USA halftone counts from 55 to 200 and metric halftone numbers from 21 to 78.
