Description
TWIN TDM is a Rockwell hardness meter with test loads ranging from 15 to 187.5 KgF. (N 147 – 1839) but also available with loads of 750 KgF. Complies with ISO-EN and ASTM standards for Rockwell testing, which has been designed for line hardness testing of thin-walled tanks with length from 180 to 2,000 mm. and diameters between 80 and 220 mm. The line in question consists of two durometers with two systems of surface preparation by means of lamellar grinding wheels, with pressure increases on the wheels through absorption of current which varies according to slats consumption. The surface preparation systems and the two durometers are mounted on two parallel lines, so that the tank may be loaded and unloaded in the same position by means of master controller.
