Advanced Digital Rockwell Hardness Tester

(Model: KH3000)


• 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 33mm. (Min dia.15mm using a goose neck)

• Can be used directly to measure Rockwell hardness for metal and plastic material.

• Provided with many features such as high measuring precision, wide measuring range with 15 Rockwell scales.

• The tester is suitable for testing of carbon steel, alloy steel, cast iron, non ferrous metal, and engineering plastic etc.
