1. Basic Information of the Instrument
Name: Automatic Rockwell Hardness Tester
Serial Number: 1704636S
Model Number:RB2000
Manufacturer: Buehler
2. Specifications and Functions
2.1. The pressure head is directly mounted on the pressure sensor, reducing the transferability error and improving the sensitivity.
2.2. The pressure head is easy to replace and it can be used at once after being plugged.
2.3. High precision grating displacement sensor can measure the indentation depth.
2.4. Fixed test bench without lifting screw is used vertically, and the test is performed by up and down movement of the indenter, avoiding the accuracy shift caused by the traditional lifting screw moving for a long time.
2.5. Initial Test Force: 3, 10Kg.
2.6. Main Test Force: 15, 30, 45, 60, 100, 150Kg.
2.7. Scale Bar: A, B, C, D, E, F, G, H, K, L, M, P, R, S, V, 15N, 30N, 45N, 15T, 30T, 45T, 15W, 30W, 45W, 15X, 30X, 45X, 15Y, 30Y, 45Y.
2.8. Experimental Force Control: fully automated closed-loop sensor control system.
2.9. Repeatability Reproducibility Accuracy GR&R<5.
2.10. Experimental Cycle: automatic, one press of the button can make automatic loading, testing and return possible.
2.11. Shape Correction: automatic correction of the test results of cylindrical concave and convex specimens.
2.12. Maximum Height of Specimen: 254mm.
2.13. Depth at Centerline: 216mm.
2.14. Conformity to Standards: EN-ISO 6508, ASTM E-18, JIS.
2.15. Specimen Illumination: 12V 30W fixed-point fiber optic illumination, adjustable brightness, no visual illusion.
2.16. Data Output: R232.
2.17. Resolution: 0.1 or 0.01HR (adjustable).
2.18. 2 120° diamond indenters; 2 sets of 1/16" carbide ball indenters (with 4 spare balls); 1 set of 1/8 carbide ball indenters (with 2 spare balls); standard V-shaped test bench and 1 Φ63mm flat test bench.
3. Function and Usage
Different experimental force can test the micro hardness of the sample and the indentation method can test the fracture toughness of the material.
