AUTOMATIC HARDNESS TESTER

Absolute measure
- Unrivalled accuracy with no misalignment and/or anomalous shoves
- All operations are fully automatically started up through only one drive
- It meets all laboratory requirements
- Full operation even in presence of vibrations, sudden changes in temperature or dusty environment


Unparalleled accuracy,repeatibility and reproducibility in all test conditions (0,1 HRC) which can be checked in operation condition
- Survey of load and indenter penetration in axis, in order to obtain an absolute hardness measure
- Graphical lighted display with high contrast to obtain clear, rapid and accurate readings. Icons facilitate the operator in identifying software functions.
- Signal for test cycle end that facilitate the operator
- The operator can automatically select test load and measure scale only though a button
- Simultaneous conversion different scales (Rockwell, Brinell, Vickers and in N mm2 resistance)

High resolution of measure 0.1 HRC or 0.01 HRC
on demand
- Fully conform to ASTM E 18, UNI EN ISO 10109 norms
- Reversibility from automatic to semiautomatic for single test.

2 years full warranty
in order to assure high technological level it contains
- Wide range of accessories in order to hold piece of every shape

Automatic control and selection of pre-loads and loads through a software in closed-ring and with load cell
- Effective statistics software incorporated with connection to printer or computer in order to supply: diagram, graph, tests list, average, standard deviation, cp, cpk.
- The instrument and its controls are ergonomically provided with security devices according to CE norms
- Software includes setting in three selection classes in order to simplify the insertion of the instrument in an automatic working line
- Programmable test load, division 0.1 second
- Automatic correction of measure on round surfaces
