HR-150A Rockwell hardness tester wholesale price

Wholesale price of R-type Rockwell hardness tester
Product overview editor
R Rockwell hardness tester is a desktop Rockwell hardness tester, which adopts Rockwell () measurement principle and is suitable for cemented carbide, carbon Rockwell hardness testing of steel, alloy steel, cast iron, 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.

It is suitable for heat treatments such as quenching and tempering. The Rockwell hardness measurement curved surface measurement is stable and reliable.
Instructions for use
Installation of R Rockwell hardness tester
The working conditions of the hardness tester are within the range of room temperature Celsius ~ degrees, the relative humidity in the room is not greater than %, and there is no vibration. In the environment. There are no corrosive media around. Unpack 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 bottom plate, use a wrench to unscrew the bolts under the bottom plate, and separate the hardness tester from the bottom plate. Take 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 (picture) at appropriate positions on the workbench so that the screw () can work normally.
Maintenance and Precautions Edit
.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 on the bottom, and it should not fall sideways, and the weights and suspenders should be removed. .During the hardness test, it is strictly prohibited to turn the variable load handwheel when adding, maintaining, or removing the test force. .The use of hardness blocks can only be carried out on the working surface. The distance between two adjacent indentations and the center of the indentation and the edge is not less than two years. 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
