Auto Twin Digital Rockwell Hardness Tester With Motorized Lifting System
New features:
Motor driving lifting mechanism make the testing more easily. Just press “START” key once, whole process will be finished automatically. No matter 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.
More testing precision than handle wheel lifting type machine which effected by human factors.
Integrated casting body with more wide iron basement leads to more stability.
Basic functions:
Twin tester--Regular Rockwell & Rockwell Superficial hardness for metal and plastic material.
Horizontal Protrudent Indenter Design, suitable also for internal and external testing.
Testing on Surfaces difficult to reach. Testing internal surface of rings and tubes with diameters over 23mm.
Testing force is set automatically according testing scale.
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.
Measuring results digitally displaying and can be printed, or transmitted to external computer
automatically by USB or RS-232 data output port.
Test value can be converted to the value of HB, HV, HK and σb value.
Curved surface correcting automatically.
The tester meeting all the following standard such as ISO 6508-2, ASTM E18.
