KHR-300&310&320
- 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.
- Modern design with Titanium metallic Silver finish
- Provided with many features such as high measuring precision, wide measuring range
- The tester is suitable for testing of carbon steel, alloy steel, cast iron, non ferrous metal.
- Automatic load cycle. The loading, dwell, unloading process of the main test force are controlled exactly to meet standard.
- 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 transformed to the value of HB, HV, HK and σb value.
- The tester meeting all the following standard such as ISO 6508-2, ASTM E18.
