Vikers Hardness Tester

Specifications

Brief Introduction

1.1   Vickers Hardness Tester is a new type high-tech product combining the optical, mechanic and electronic techniques with a novel and pleasing appearance, favorable operational functions and reliability, and hence it is an ideal instrument for the testing of micro-hardness.

1.2   The instrument is made with a precise design in the field of mechanics, CPU control of the testing in the electric field, and adopted the highly clear optic measuring system in the field of optics as well. Besides, inputting by means of the touch keys on the operating board, the instrument has multiple functions such as the selection of the Vickers or the Knoop measuring methods, the presetting of the dwell time for test force, regulation of the intensity for measuring light source and the indicating testing numbers, etc. After readout the diagonal line length of indentation and key in it through soft keys, the hardness value will be shown on the screen.

1.3   According to the particular requirements of the client, the instrument can be equipped with CCD device. The instrument is suitable for testing the micro and thin pieces, the parts with the permeated and coated surface, it is also fit for testing Vickers and Knoop hardness value for the crisp materials such as the agate, glass, ceramics and it is, therefore, an ideal hardness measuring instrument for the scientific research institutes, the universities and colleges, the industrial production units and the metrological institutes using with for studying and measuring.
