Rockwell DAKOMASTER 300 

DAKOMASTER 300

Automatic hardness tester for Rockwell, Superficial Rockwell, Brinell, Vickers and Shore test methods in compliance with ASTM and ISO hardness standards. Dakomaster 300 is a top level bench hardness tester with a wide touchscreen allowing easy test planning and a clear view of results. Statistics and diagrams are automatically generated and can be stored with test session in the large archive. User friendly interface with conversion tables and round correction values for tests on convex cylindrical surfaces or various diameters. This hardness tester is fully motorized for fully automatic test cycles, with a long motorized head stroke and a large base. Load forces are applied through load cells and electronically controlled in Closed Loop (Pat. Affri). Hardness testing on all metals: iron, steel, tempered steel, cast iron, brass, aluminum, copper and metal alloys. Heat treatment, hardening, nitriding, cementation and hardfacing. Hard and soft plastics.

ONE BUTTON MEASUREMENTS

Just press one button and the hardness tester’s head moves down to make contact with the sample’s surface, locking it. The hardness test cycle will automatically begin in automatic succession without breaching a phase. Within seconds results appear.

CLOSED LOOP TECHNOLOGIE (PAT. AFFRI)

Load forces are applied through load cells and controlled in “Closed Loop” with a frequency of 1 khz, assuring perfect linearity in every range. Results are not affected by any structural deflection, misalignment or vibration.

REPEATABILITY AND REPRODUCIBILITY

When testing unstable samples or deflective parts, the AFFRI System will follow the sample without losing contact. Accurate measurements even on the first test will eliminate the need for repeated tests. The R&R data is at the top of its class.

MOTORIZED TESTER'S HEAD

Automatic movement with automatic stop when contact is made with samples. Total of 300 mm of motorized vertical stroke. The approach of the head moving to the piece as opposed to the piece moving to the head allows for more accurate, stable and safe measurements.

LARGE BASE

The hardness tester’s wide work table base is capable of bearing masses beyond 1000 kg which allows for steady hardness measurements on bulky or irregular pieces. It also offers a comfortable working base for small pieces.

COMPACT TESTER'S HEAD

The measuring head of the DAKOMASTER 300 hardness tester is small and compact. It can easily test inside tubes with a diameter of 150 mm and above.

DAKOMASTER SOFTWARE

The pre-installed software controls the whole instrument during the entire cycle avoiding operator errors:

This software is user friendly in and easily managed by touchscreen. The software, developed by the AFFRI team, is a powerful analysis system, including fast test settings, statistics of results, live graphs and the ability to store data or test sessions.
