Used to determine the depth of penetration of a flat headed pin into pressed raw ceramic tiles. Indispensable for producers of floor and wall ceramic tiles, especially with single firing processes. Calibrated spring system, with special reading comparator reset process that can be carried out only occasionally, that makes the relative tile measurements in a few seconds. The mod. DM/34 penetrometer therefore makes it much easier to carry out daily checks on pressing uniformity. The large stainless steel base makes it easy to perform tests in the centre of the sample, up to a size of 40×40 cm, and up to a size of 70×70 cm upon the model. Main body and various supports in stainless steel. Accurate finishes. Complete with various accessories for use and maintenance, 5 flat head pins with areas of 0.75-1.00-1.50-1.75-2.00 mm2, that, together with an additional 3 kg calibrated spring and a special supporting head, allow the instrument to be used on a wide range of pressed materials, from the softest to the hardest. The 1.50 mm2 pin and the 4 kg calibrated spring are already mounted on the device.
