 Product Introduction
 
DHB***0 Brinell Hardness Tester is equipped with a portable Brinell hardness automatically measuring system and adopted a digital pick up camera hence make a clearer image. It can analyze the image accurately and measure the indentation at high speed automatically. Besides, the instrument has such functions as: accurately calculate the hardness value and indentation diameter in real time, measure single specimen and series specimens, exchange hardness scales according to ASTM/international hardness exchange table, save the data and image, query database, etc. Whole system with small and de1icately design can be easy installed and simple operated.
   The Brinell Hardness test that shows the largest indentation among all the hardness tests is able to reflect the comprehensive features of the material, and the test is unaffected by the organization micro-dioptre and the compositional unevenness of the specimen; and hence it is a hardness testing with high precision. The Brinell hardness test is widely used in such industrial fields as metallurgy, forging, casting, steel, hardened steel and nonferrous metals industries, as well as in the laboratories, universities, colleges and scientific research institutes
 
Main Features
  DHB***0 electronic Brinell Hardness Tester is a unified product combining the precise mechanical structure with the computer control by means of the mechanical and electrical circuit system, and so it is the more advanced brinell hardness tester in todays world. The instrument adopts the motorized test force application without weight blocks, and uses 0.5%o alluracy compression sensor to feedback the information and the CPU control system to automatically compensate the test force lost during the testing. The test force and the load dwell time can be directly set pressing the selected keys on the touch-keyboard, with reliable repetition, precise reading and easy operation.
