HARDNESS
TESTER HLN-11
HLN-11
is an advanced hand-held hardness tester distinguished by its
high accuracy, wide measuring range, and simplicity of
operation. It is suitable for testing on various conditions.
- In-suit
testing of individual parts, or components in assembled
machines
- Mould
surface of a die
- Heavy
components e.g. roll for rolling mills, etc.
- Quick
analysis of pressure vessels, turbo-generator sets, etc.
- Testing
in a production line e.g. crankshafts, cylinder blocks, etc.
- Material
identification
- Display
test results in all various hardness scales (HRB, HRC, HB,
HV, HSD, HL)
- Test
at any angle, even up-side-down
- Convert
to Ultimate Tensile strength
- Immediate
conversion between harness scales, and print-out if desired
- Input
and print-out of test number and date
- Input
and print-out of material type, and test direction
- Print-out
of test results via integral printer if needed
- Battery
low indication
- Protective
carrying case completeing with test block, support ring,
cleaning brush and battery charger
- Seven
impact devices available: D ,DC ,DL ,D+15 ,C ,E ,G
