Linen Provers
Linen Provers. Enable the number of threads and weave to be counted to the inch or centimetre to determine the quality and strength of the material. Also used extensively in the print trade and photography, to test the quality of the paper and the pixels respectively. A linen tester is ideal for looking at watermarks, stamp perforations etc. The hinge mechanism should not wear out unlike cheaper models.
