2143 TRS-M

Super Rockwell Hardness Tester

The 2143 TRS-M device in accordance with GOST 23677 is intended for measuring the hardness of metals and alloys according to the Super Rockwell method in laboratory conditions.

The device allows you to measure hardness in accordance with GOST 22975.

The device belongs to the group of hardness testers that have a manual supply of the product to the tip, electronic measurement of the indenter penetration depth with digital indication of the measurement result, automatic zeroing of the reading device, exposure of the product under load, set limits of hardness tolerance, visual breakdown of products into three groups: hardness LESS-NORMAL-MORE, mathematical processing of measurement results from a series: finding the average, largest, smallest value and variation of readings.
