2. Construction: The tester comprises the interchangeable test head N1A 001 and one of the light metal cast C clamps, with quick release spindle.
3. Test method equipment available for: All Rockwell, Brinell and Vickers tests from 147 N to 1840 N (15–187.5 kgf).
4. Measuring accuracy to EN ISO 6508.
5. Through the use of adaptors it is possible to fit adjustable load test units: N1P 000 – for plastics testing to EN ISO 2039-1, N1R 000 – for Rockwell testing to EN ISO 6508 – 60, 100, 150
N1S 000 – for Super Rockwell testing to EN ISO 6508 – 15, 30, 45, N1U 000 – for Rockwell 30, 150, 187.5.
6. Operation: The part to be tested is clamped between the anvil and the test head, after which the load is applied to the indentor.
7. Subsequently the reading is taken from the dial gauge.
