2. The thickness of the sample should not be less than 4mm, and the size of the sample should ensure that the distance between the center of each measurement point and the edge of the sample is not less than 10mm, and the distance between the centers of each measurement point is not less than 10mm. The recommended sample size is 50x50x4mm or 50x4mm in the middle.

Mechanical Structure

Mainly composed of a rack, a pressure head, a loading device, an indentation depth indicator instrument, and an electronic control device.

Precautions

1. During the experiment, it is necessary to ensure that the applied force is perpendicular to the surface of the specimen, and that the supporting surface of the specimen is in good contact with the workbench. The loading during the experiment should be smooth and not subjected to impact or vibration.
2. The installation of the indenter or replacement of the workbench should be tested several times to ensure that the hardness tester is in working condition before conducting the hardness test.
3. The number of trials in each experiment shall not be less than 3 times.

Maintenance of RT-1077 Hardness Tester

1. The hardness tester must be installed in a dry place, with no vibration source, dust or corrosive gases nearby.

2. When using a hardness tester, it must be measured within the specified hardness range. If the hardness range of the tested sample cannot be determined, the load should be gradually increased from small to large.
3. The casing of the hardness tester should be well grounded, and the power should be cut off after use.
4. The hardness tester should be kept clean regularly and covered after use to prevent dust from entering and rust.
