Ultrasonic hardness tester checks hardness by static loading method with Vickers type diamond indenter. Diamond indenter mounted on vibration rod gives vertical vibration in ultrasonic frequency. SH-22 acquires hardness value from frequency change at indenter contact on test object. SH-22 is widely used for hardness checks of products and facilities which cannot be tested by destructive method, in many and various fields.

• Handy and portable instrument for testing at sites.
  
• Very small indentation (Under 0.2mm approx.)
• Suitable for checking on thin quenched/nitride/carburized layer.
• Indication in five scales available (HV, HRC, HRB, HS, HBW).
