Reference Hardness Tester for calibration laboratories.
This highly accurate Hardness Tester is designed for laboratories calibrating Test Blocks.
It includes Affri System technology and a fully automatic system to perform calibration in accordance with the International Standards ASTM, EN ISO-JIS.
Designed for Vickere and Brinell as per ISO 6507-3, ISO 6506-3 Standards

Integral AFFRI System
Absolute measurement
The Start button initiates an uninterrupted test sequence comprising:

• Approach the piece.
• Clamping.
• Impression of reference surface.
• Complete measurement cycle with subsequent release.

The result is not influenced by deflections during the test cycle.
Large and fixed table supporting test pieces.

Designed for different applications:

• EN ISO 6508-3 for Rockwell.
• EN ISO 6508-3 for Superficial Rockwell.
• EN ISO 6506-3 for Brinell.
• EN ISO 6507-3 for Vickers.

The excellent accuracy and repeatability fully meet the requisite standards. A table of practical results obtained on AFFRI machines and another reference machine shows.

AFFRI’s high comparable performance (?):
The integral Affri system of this machine operates on the same principle as that adopted in the regular production machines shown this catalogue.
