JFE Advantech Hand-Held Hardness Checker SONOHARD®
เครื่องวัดความแข็งระบบอัลตราโซนิค ยี่ห้อ JFE Advantech รุ่น SH-21
SH-21 Hand-Held Hardness Checker SONOHARD®
The SH21 is very easy to use and requires no special knowledge of hardness testing in order to operate the instrument. The unit includes all four hardness scales and you can switch between them at the touch of a button.
* Quick measurement (few seconds).
* Best repeatability and precision.
* Direct reading of hardness.
* Easy to use hand held probe can be quickly applied to a variety of surfaces from any direction.
* Easy to use – no prior experience of hardness measurement techniques required.
* Built in memory for data and calibration points.
* Measures Vickers, Rockwell, Brinell and Shore scales.
* Interchangeable probes for use with different surface profiles, pipes, concave surfaces, gears valves etc.
* Portable works with rechargeable lithium ion battery.
Applications
- Evaluation of carburizing, standard quenching and high-frequency quenching
- Weld hardness measurement for welded structures (tanks, hulls, bridges, steel towers ,etc.)
- Hardness measurement for a gear tooth flank (narrow area)
- Measurement of structural strength or hardness of a facility
- 100% online inspection for components (engine valves, rack bars, crankshafts, bearings, etc.)
