Digital Display Handheld Hardness Tester Meter

Product Description

Digital Display Handheld Hardness Tester Meter 

Product Description

Application Fields:

1. The bearings and other parts, heavy work-pieces, metal material, pressure vessel, failure analysis of turbine generator unit and equipment
2. Mechanical or permanent assembly components have been installed, the test space is very narrow, requires the original record regular test results

1. Large work-piece within a wide range of more rapid test measurement site

 

Optional Impact Device:
 

       
      
Measuring Conditions:

1. The weight of measuring object ≥ 2kg.
2. The thickness must be ≥ 10mm.
3. The surface roughness must be ≤ 1.6μm.

Tips: If do not meet the above conditions, the measuring object should be laminated with steel substrate by coupling agents.
