Rockwell C Hardness Tester Rockwell Hardness R Scale Rock Well
Hardness Test HR3300
New features:
- The test force are applied via a closed-loop control unit with a
load cell, a DC motor and an electronic measurement and control
unit replace traditional dead weights. The result is highly
accurate measurements at all test loads up to 0.5%.
- Simple plug - and - play tech allows for much more quick and easy
installation than traditional weights type machine.
- Manual handle wheel pre-load. Automatic main-load and testing cycle.
- Extended dolphin nose allows verticaltest height of 300mm and
throat depth of 220mm.
- Integrated casting body with more wide basement leads to permanent
stability.
- RS232 and USB port to PC.
Basic functions:
- Twin tester--Regular Rockwell & Rockwell Superficial hardness
for metal and plastic material.
- Horizontal dolphin nose Indenter is suitable also for internal and
external testing.
- Testing on Surfaces difficult to reach. Testing internal surface of
rings and tubes.
- Provided with many features such as high measuring precision, wide
measuring range with 30 Rockwell scales.
- The tester is suitable for testing of carbon steel, alloy steel,
cast iron, non ferrous metal.
- Automatic testing cycle: Lifting of part, pre-loading, loading,
dwell, unloading, results will be finished automatically.
- Measuring results digitally displaying and can be printed, or
transmitted to external computer automatically by USB port.
- Test HR value can be converted to the value of HB, HV, HK and σb
value.
- The tester meets all the following standard such as ISO 6508-2,
ASTM E18.
