Product Description
Small / Large Metal and Alloy Articles Hardness Measuring Tester, Ultrasonic Portable Hardness Tester HUH-2
Product information:
It is intended for measuring hardness of metal and alloy articles with Rockwell, Brinell, Vickers. It consists of the dynamic transducer (sensor) and the electronic module.
The principle of tester operation is based on determination of frequency change in free oscillation of the indenter (an acoustic resonator with Vickers diamond pyramid) subjected to the constant force of 50 N.
Advantages:
- Measuring hardness of both small and large articles
- Measuring hardness of complexly shaped articles, with hard to reach places, in various spatial positions
- Convenience and ease of use
- PC-connectable via RS-232C interface
- High measuring performance
- Power source discharge indication and display illumination
- Graphical display with lighting
- Storing 1000 hardness measurements in the nonvolatile memory
- Supply of reference blocks on request
