Product Description

AMT67D AMT67DL Leeb Hardness Tester
 
Feature:
1. Intelligent simple: No key "fool" type operation, directly shows the most commonly used on the Leeb scale and Rockwell values.
2. Small and portable: Small, portable instrument, integrated design without connecting cables, improves the reliability
3. OLED display: Can clear display under direct sunlight, suitable for all kinds of lighting conditions
4. Born colorful: Self-expression with unique colors, show the unique personality
5. Accurate Measurement: High precision of measurement circuit guarantee value error for ±0.5%(HLD=800), repetition rate value for 0.8%
6. Support for multiple hardness standard: HL, HV, HRA, HRC, HRB, HB, HS
7. Massive capacity data storage: The unprecedented mass storage leads the technology trend. It can save 270 hardness measurement data, each group including average, hardness standard .
8. 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.
9. Charge as you want: USB charging, compatible with most cell phones and other digital product interface.
