N4 portable hardness testers
Portable hardness tester, 147 − 1840 N (15 − 187.5 kgf)
Capacity: 0 − 20 / 145 / 235 / 335 mm
Rockwell EN ISO 6508, ASTM E−18
Plastic testing EN ISO 2039
HBT and HVT methods
The N4 portable hardness tester possesses a clamping device consisting of clamp in light-alloy with quickly adjustable threaded spindle and clamping toggle. According to customer’s request, test unit N1A 001 with spring sleeve or one of the load adjustable test units can be selected.
Operation:
The part to be tested is clamped between the anvil and the test head, after which the load is applied to the indentor. Subsequently the reading is taken from the dial gauge.
Load-adjustable test unit:
N1P 000 − for plastic testing in compliance with EN ISO 2039−1 − 5, 13,5, 36,5, 98 kgf
N1R 000 − for Rockwell test in compliance with EN ISO 6508 − 60, 100, 150 kgf
N1S 000 − for Super Rockwell test in compliance with EN ISO 6508 − 15, 30, 45 kgf
Test methods:
All Rockwell methods in compliance with EN ISO 6508, ASTM E−18. HBT non-standard in depth methods are possible in load range 294 − 1840 N (30 − 187.5 kg).

N6 portable hardness tester
The N6 portable hardness tester consists of test unit N1E 000 (complete with dial gauge, dial gauge cover and spring sleeve) with load lever and Intest sensor with tensioning nut, clamping clip and spring link, including test sample. The standard design consists of load level 62.5, HRC hardness value indicator, device case, hardness comparison table and instruction manual.
Operation:
The testing machine is positioned in the bore and fixed by clamping action. The test load is applied via hand lever. Subsequently the reading is taken from the dial gauge in HRC values.
Application:
For bore diameters from 36 to 110 mm.
Insertion depth up to 400 mm.
