These laboratory instruments are used for determining the dimensional characteristics of ceramic tiles, including length, orthogonality, planarity, warpage, edge straightness, and side curvature, all in accordance with the UNI EN ISO 10545-2 standard.
Measurements are performed by taking the difference between a calibration tile and the ceramic tiles being tested.
Various models are available, differing in tile size compatibility, whether they are tabletop or freestanding, and if they feature analog or digital comparators.
