DESIGNED FOR MILLIONS OF TESTS 24/7

SUPER-FAST AUTOMATIC HARDENSS TESTER

Complete automatic hardness test cycle including the clamping of the piece, application of the load, hardness measurement, release of the piece, return to starting point and it is ready for a new test. High volume measurements, the tester can easily be introduced into the conveyor lines, yielding up to 1500 test per hour.

Test loads

From 3 to 187,5 kgf (From 29,42 to 1839 N) – As optional 250 kgf (2452 N)

Rockwell and superficial Rockwell ISO 6508 / ASTM E-18

HRA – HRB – HRC – HRD – HRF – HRG – HRL – HRM – HRR / HRN – HRT
