Rockwell hardness tester
ZwickRoellRockwell hardness testerUsed in the classical rockwell method, metal surface rockwell method, such as plastic ball indentation test method of depth measurement.
With the help ofRockwell hardness tester, poor available depth measuring pressure head produced by the residual indentation depth.Under the specified test load, the pressure head through the deeper the sample surface, measured material more soft.The most widely usedRockwell hardness test methodIs in compliance with ASTM E18 and ISO 6508 standard metal standardized test method.In the plastic industry, these includeUp to the standard of ISO 2039-2 and ASTM D785 rockwell hardness test, as well asUp to the standard of ISO 2039-1 ball indentation hardness test.

What is the difference between rockwell hardness tester?
rockwellHardness tester is designed for the use of differential method, the hardness of the material was tested.
Typical of rockwell hardness testing machine by the load function, pressure head and test head and measurement sensors.DuraJet,ZHR touch screenandZHR8150CLModel is a software control type hardness testing machine, has automatic closed-loop load applied and fully automatic indentation evaluation function.ZHRInstruments used farmar system operation.
Using the software control instrument, you can visit a lot of features, including the use of templates, export the result and so on.
Rockwell hardness testThere are a number of applications.It is not only used for material properties, according to the determination of hardness and molding process is also used in the production and purchase department rapid and effective test.This helps to ensure the materials meet the requirements, and exert the best performance when used for its intended application.
In ZwickRoellRockwell hardness testerResearch and development process, we especially considering the following aspects:
- High precision and durability
- Operation is simple and intuitive, in order to minimize error
- Meet the future needs of test software
Rockwell hardness tester how to work?
Rockwell hardness tester using conical diamond formation of indentation on the material under test.After completion of pre load applied, accurate exert main load according to the specified time range.Then, remove the main load, then measuring the depth of the cone penetration material difference and calculate the hardness value.
