HST-KHT900-M Automatic Rockwell Hardness Tester
Product Description
Product introduction
-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.
-Automated Z-Axis. Just press START key once, entire test process will be finished automatically. Regardless of the the size of the sample, the position of the sample, the distance between the indenter and sample surface. The sample will be auto-lifted to approach the indenter and finishing testing automatically.
-Higher precision than handle wheel lifting/dead weights type machines which can be affected by user interaction.
-Extended dolphin nose allows vertical test height of 300mm and throat depth of 220mm.
-Integrated casting body with more wide basement leads to permanent stability.
-Built in micro-printer and USB port to PC
Product 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
