Hardness Tester Features:
The test force is 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 hardness test measurements at all test loads up to 0.5%.
Simple plug - and - play tech allows for much more quick and easy installation than traditional dead weight type machines.
Automated Z-Axis .Just press START key once, entire test process will be finished automatically. regardless of 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 finish hardness testing automatically.
Higher precision than handle wheel lifting/dead weight type machines which can be affected by user interaction.
Extended dolphin nose allows vertical hardness test height of 11.8" and throat depth of 8.6".
Built-in micro-printer.
Twin hardness tester --Regular Rockwell & Superficial Rockwell hardness for metal and plastic material.
Horizontal dolphin nose Indenter is suitable also for internal and external hardness testing.
Rockwell Hardness Testing on Surfaces difficult to reach. Hardness Testing internal surface of rings and tubes.
Provided with many features such as high measuring precision, wide measuring range with 30 Rockwell scales.
The Rockwell hardness 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 displayed and can be printed with its built-in thermal Mini-Printer.
Test HR value can be converted to the value of HB, HV, HK and σb value.
The tester meets the following standards: ISO 6508-2, ASTM E18.
