This instrument is a portable measuring instrument, it can quickly, lossless, high accuracy of the hardness of common metal materials measurement. It can be used in both laboratory and engineering sites. Through the instrument measurement condition setting, it can meet a variety of measurement demands. This instrument can be used in manufacturing, metal processing industry, chemical industry, commodity inspection and other testing fields. It is a necessary instrument for non-destructive hardness testing of materials.
Feature：
1 、Small and portable
The instrument is compact, portable and integrated without connecting cables, which have high reliability.
2 、Industrial bright OLED display
It can also be displayed under direct sunlight clearly, suitable for various light conditions
3 、The accurate and high-precision measuring circuit ensures that the value error is ±0.5%(HLD=800) and the value repeatability is 0.8%
4 、 Support a variety of hardness
HLD 、HRC 、HRB 、HRA 、HB1 、HB2 、HV 、HSD
5 、Automatic calculation
The average hardness can be calculated automatically
6 、Hardness
Support "forged Steel" material
When the D-type impact device is used to test the "forged steel" sample, the HB value can be read directly without manual table reference.
7 、Convenient charging
USB charging, compatible with most mobile phones and other digital product interface
3 、Principle of measurement
With the specified quality of the impact body under the action of elastic force, with a certain speed of impact on the surface of the sample, with the punch 1mm away from the surface of the sample rebound speed and impact speed ratio of the hardness value . The calculation formula is as follows:
HL= 1000×VB/ VA
Leeb Hardness Range Rebound
Impact speed
