} Product Overview
- Rockwell hardness tester is a desktop Rockwell hardness tester, which adopts Rockwell (R) measurement principle and is suitable for cemented carbide, carbon steel, alloy steel, cast iron, Rockwell hardness testing of non-ferrous metals and other materials can be widely used in testing, scientific research and production in metrology, machinery manufacturing, metallurgy, building materials and other industries.
The Rockwell hardness tester adopts the Rockwell measurement principle and can directly measure Rockwell hardness. It has the characteristics of good structural rigidity, simple operation, stable indication value and convenient maintenance. Suitable for Rockwell hardness testing of cemented carbide, carbon steel, alloy steel, cast iron, non-ferrous metals and other materials.

3} Scope of application
- The Rockwell hardness tester has a very wide range of applications. It can measure the Rockwell hardness of ferrous metals, non-ferrous metals, and non-metallic materials
It is suitable for quenching and tempering, etc. Heat treated Rockwell hardness measurement curved surface measurement is stable and reliable.
} Instructions for use
- Installation of Rockwell hardness tester
. Working conditions of the hardness tester
. Within the range of room temperature Celsius ~3 degrees
3. Indoor relative The humidity is not greater than,
. In a vibration-free environment
. There are no corrosive media around.
.Unpacking the hardness tester
.Remove the four nuts at the bottom of the box, lift and remove the box, and take out the accessory box.
. Raise the base plate, use a wrench to unscrew the bolts under the base plate, separate the hardness tester from the base plate, and lift out the hardness tester (pay attention to safety).
.The unpacked hardness tester should be placed horizontally on a stable workbench, and its levelness should not exceed /. At the same time, make holes at appropriate positions on the workbench (picture) so that the screw can work normally.
} Maintenance and Precautions
.Test personnel should abide by the operating procedures and be able to frequently use standard blocks to calibrate the instrument before and after the test. For hardness testers that are not frequently used, the hardness must be measured on the standard block several times after starting up. After stabilization, the test piece can be tested again.
.When transporting the instrument, it should be carried with the bottom, and it should not fall sideways, and the weights and suspenders should be removed.
3. During the hardness test, it is strictly forbidden to turn the variable load handwheel when adding, maintaining, or removing the test force.
.The hardness block can only be used on the working surface. The distance between two adjacent indentations and the center of the indentation and the edge is not less than 3, and its service life is two years.
.The hardness meter should be calibrated periodically at least once a year to ensure the accuracy of the hardness meter.
.Common troubleshooting of hardness tester When the hardness tester fails, you should contact the relevant unit for repair. Generally, common faults can be solved by yourself
