Product information

Ultrasonic Hardness Tester SH-22


BRAND: JFE Advantech – Japan

Perfect for hardness check on narrow/ curved surface of quenched material

  • Narrow/ curved surface can be measured by small diameter probe (comparing with our model SH-21)
  • Hi durability – More than 1 million measurements.
  • Measurement in just 2 seconds.
  • Static loading method with Vicker indenter.
  • Tiny indentation (approx. 0.1mm).
  • Measurement is not effected by material/ mass of measuring base.
  • Measurement can be done in all directions.
  • Free from periodic parts replacement by adoption of static loading method
  • Upper/ lower limit alarm setting available.
