Model No. 900-410
1 General description
The 900-410 Digital Rockwell Hardness Tester can be used directly to measure the most popular regular Rockwell hardness scales and it can quickly convert that hardness value into HB, HV, HLD, HK and many other scales. Loaded with many useful features such as ultra precise results, wide measuring range, scale and test force selectable, automatic main test force loading/unloading, high resolution digital display and USB data storage. The 900-410 is suitable for testing hardness of carbon steel, alloy steel, cast iron, non-ferrous metals and engineering plastics.
The tester meets the following standard: ASTM E18, ISO 6508-2, and BS EN ISO6508-2.
