HB-3000S Brinell Hardness Tester with New Touch Screen New Usage to Lead Change of Hardness

1. Brief Introduction

1.1 Hardness is one of the important indices of material mechanical performance. And hardness test is the important means to determine metal material or the quality of product parts. Because of the corresponding relation between metal hardness and other mechanical performance, therefore, most metal materials can be measured the hardness to approximately calculate the other mechanical performance, such as strength, fatigue, creep and wear.

1.2 The instrument controlled by single-chip microcomputer,acquire signals by sensor,loading by stepping motor,It’s a closed-loop control system.  Brinell hardness test is mainly used in hardness measurement for cast iron, steel products, nonferrous metals and soft alloys, etc. Besides it can be also used in hardness measurement for some nonmetal materials, such as rigid plastics, bakelite, etc.

1.3 The instrument uses a new touch screen,with new usage to lead the change of  Hardness.

1.4 Performance Standards:    GB/T231.1  GB/T231.2

2. Main Technical Specifications
