Product features
1.Intelligent simple "fool" type operation, directly shows Leeb scale and Rockwell values
2. Small and portable Small, portable instrument, integrated design without connecting cables, improves the reliability
3.Industry highlights, OLED display Can clear display data under direct sunlight, suitable for all kinds of lighting conditions
4.Accurate Measurement High precision of measurement circuit guarantee value error for ±0.5%(HLD=800),repetition rate value for 0.8%
5.Support for multiple hardness standard HL、HV、HRA、HRC、HRB、HB、HS
6.Massive capacity data storage The unprecedented mass storage leads the technology trend. It can save 270hardness measurement data, each group including average, hardness standard.
7.Support ‘Forged Steel’ material When impact type D device test sample "forged steel" it can be read directly HB values, without manual look-up table. Hardness value is preset upper and lower limit, automatic alarm beyond the scope, convenient for the user batch testing.
8.Charge as you want USB charging, compatible with lots cell phones and other digital product interface
Measuring Principle
A predetermined mass of the force of the impact body, the impact surface of the sample at a constant speed, with the punch1mmaway from the sample surface at the impact velocity and rebound velocity calculated from the ratio hardness value. Calculated as follows： HL=1000×VB/ VA HL——Leeb Hardness VB——The speed of rebound VA——Impacting Speed of impact body Impact device output signal Schematic diagram is as follows
