ADVANCED ULTRASONIC HARDNESS CHECKERS
SONOHARD SH-21
 |
|
| Measuring stand (option) |
| When attached to the measuring stand, the SH-21 can be used as a stationary hardness checker. The small, light body (weighing 2.5 kg) can be carried easily in the field. |
|
POINT 1 |
Most suitable for measuring quenching hardness of narrow sections, enclosed sections, and internal/external gauge sections |
POINT 2 |
Supports four scales, HV, HRC, HS, and HB |
POINT 3 |
Capable of storing up to 2000 points for data and 10 points for calibration values |
POINT 4 |
Applicable to product inspection also for its undetectable indentation |
POINT 5 |
Enabling measuring of probes in any direction of up, down, left, and right |
|
Applications
● Evaluation of carburizing and quenching, and high frequency quenching
● Weld hardness measurement for welded structures (tank, hull, bridge, steel tower, etc.)
● Hardness measurement for a gear tooth flank (narrow area)
● Measurement of the hardness of a facility or a structure's strength
● 100% online inspection for components (engine valve, rack bar, crankshaft, bearing, etc.) |
Specifications
● Measuring indenter: Diamond indenter for Micro-Vickers (with an angle of 136º between opposite planes)
● Measuring load: 20 N (approx. 2 kgf)
● Measuring range: HV100 to 999, HRC10.0 to 70.0, HS20.0 to 99.9, HB85 to 550
● Reproductivity: HV: ±3%rdgHV, HRC: ±1.0HRC, HB: ±3%rdgHB, HS: ±1.0%HS
● Power supply: 100 VAC, or rechargeable lithium ion battery
● Minimum target size: 15 mm (width) x 15 mm (length), Thickness: 7 mm |
If measuring conditions are other than the above, the SH-21 must be set on a table of at least 50 mm (diameter) x 15 mm. Ensure close adhesion to the table with oil to increase the apparent weight. |
