A linen tester is a strong magnifier with a built in measuring scale that is usually used for fieldwork and can be folded flat and easily stored.

Originally the linen tester checks the quality and measure the number of threads within a certain area of fabric.

Today, Linen testers measure line width and check the registration of color separations in the field of printing and publishing.

Linen testers are also used in other industries. For example, to measure the line of bar codes, agriculture research and maintenance while spotting microscopic bugs in fruit and maize crops.
