BRAND: JFE Advantech – Japan
Perfect for hardness check on narrow/ curved surface of quenched material
Product information
Ultrasonic Hardness Tester SH-22
Features
- 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.
