HRLS-150 Touchscreen Digital Rockwell Hardness Tester

Description

Product Introduction:

The HRLS-150 touchscreen digital Rockwell hardness tester is our company’s next-generation, high‑tech product—multifunctional, highly accurate, and exceptionally stable. It features a modern, sleek design with an integrally cast housing that ensures superior stability. Its touchscreen interface is menu‑driven, offering simple, intuitive, and convenient operation. The measurement system employs a grating sensor and computer control, with hardness values displayed directly on the LCD screen, making it a fully electromechanical hardness testing instrument. It can automatically convert among various hardness scales and determine the minimum specimen thickness. When testing cylindrical specimens, it automatically applies correction factors. A built-in printer enables easy retrieval of test results. With automated operation, it eliminates human error in handling and reading measurements.

Main uses and scope of application:

The Rockwell hardness test measures the depth of indentation, with the hardness value read directly from the indicator. This makes it simple and convenient to operate, easy to master, and highly efficient, making it well suited for the inspection of batch‑produced components. The Rockwell method can employ either a diamond indenter or a hardened steel ball, enabling measurement of both hard and soft materials and offering a broad range of applications. Consequently, Rockwell hardness testing is widely used in manufacturing, serving as a primary means of assessing product quality and determining optimal processing parameters. Rockwell hardness testers are commonly employed by manufacturing enterprises, colleges and universities, and research institutions for hardness testing, as well as for educational and research purposes.
