NHRS-150 Digital Rockwell Hardness Tester - Precision & Trustworthy

The Digital Rockwell Hardness Tester uses the method of measuring the indentation depth, and the hardness value can be directly read from the indicator. Therefore, it is simple and convenient to operate, easy to master, and has high work efficiency. It is suitable for the inspection of batches of parts and components. In the Rockwell hardness test method, diamond indenters and steel ball indenters can be used, which can measure both harder and softer specimens, and has a wide range of applications. As a result, the Rockwell hardness tester is widely used in production and has become the main testing means for inspecting product quality and determining reasonable processing techniques. The Rockwell hardness tester is a commonly used testing instrument for hardness tests, teaching and scientific research work in manufacturing enterprises, universities and colleges, and scientific research institutions.

Product Detail

Features

● It has a novel appearance and adopts a menu-based interface, which is user-friendly.

● The measuring device utilizes a light shed sensor and computer control, and the hardness indication value can be directly displayed on the LCD screen.

● It can automatically convert various hardness parameters to each other, identify the minimum thickness parameters of the specimen and conduct mutual conversions. Moreover, it can identify the minimum thickness of the specimen and measure the ambient temperature during the test.

● It has a built-in printer for easy reading of relevant test results. Besides, automatic operation is achieved to eliminate human operation and reading errors.

● It is suitable for hardness determination of ferrous metals, non-ferrous metals and non-metallic materials.
