Structure and use

﹡HMI is a small, lightweight, accurate portable hardness tester.

© ~ Instruments CFixtures, and hardness measurement of screw head.

© ~ Can test plane or curved surface parts, replacement parts as long as can be caught, and the surface perpendicular to the head can be tested.

﹡HMI is used in the production of test and acceptance test can replace the precision of Leeb hardness tester.

Characteristics of the instrument
﹡ Rockwell hardness test in accordance with the principle of test and test conditions, the test results and reliability.

﹡ Instrument parts, hardness test after clamping without moving parts.

﹡ Test operations quickly and easily, without prejudice. ﹡ The readings of the micrometer mechanism, accurate, easy and reproducible.
Cm and desktop-like accuracy, error is not greater than 1.5HRC.

Technical parameters

Test force: 10kg
Total test force: 60kg, 100kg, 150kg
Pressure: 120 ° diamond Cone, 1.588mm carbide ball
Indication error: meet the GB/T230.2
Repeatability: meet the GB/T230.2
Resolution: 0.5HR
Application: steel, copper, aluminum and other metal.

Application note

﹡ Compared with small hardness tester, c-type hardness tester using a clamping and similar drum readings of the micrometer, institutions, good stability, repeatability, high accuracy, should be preferred.
