Cast Iron Hardness Testing Machine HR3300 High Stability 690mm × 280mm × 860mm

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.
