Product Introduction
1. Hardness is one of the often-used mechanic characteristics of the material while the hardness testing is an important method to judge the quality of the metal material or its component parts. The hardness of the metal is correspondent to its other mechanic characteristics, and so its mechanic characteristics such as the strength, tiredness, wriggling and wearing out can be tested out approximately through its hardness testing.
2. Digital Double Rockwell Hardness Tester with a novel and pleasing appearance, full functions, easy operation, clear and direct-viewing display, and stable performance is a high-tech and new product combining the mechanic and electric features. This tester is able to measure the Rockwell and superficial Rockwell hardness value with all scales. Its main function is as follows:
    2.1 The Selection of all hardness scales for Rockwell and superficial Rockwell.
    2.2 The hardness values exchange among various hardness scales.
    2.3 The selection of dwell time for hardness test.
    2.4 The revising of the value for year, month and date.
    2.5 The RS232 serial communication is supplied to clients for the functional expansion.The Present hardness tester with the storage function can be browsed the hardness testing page and output the hardness testing results with printer.
