Versatile and Reliable Hardness TestingThe HR-150A Portable Rockwell Hardness Tester is designed for efficient testing in a variety of environments including production floors, workshops, and laboratories. Its rugged cast iron construction and bench mount design ensure stability during operation, while its simple manual controls facilitate precise on-site measurements without the need for electricity. Dial indicator display and premium accessories, such as different indenter types and test blocks, provide users with all necessary tools for accurate, repeatable results.
Easy Operation and Wide ApplicationNo power supply is needed-simply operate the manual controls to apply the preliminary and total test forces. The tester is suitable for large metal components due to its generous specimen size capacity (up to 170 mm height and 160 mm depth of throat). The immediate response time, high accuracy (following ISO/ASTM standards), and resolution of 0.5 HR make it ideal for quality control in manufacturing and metal fabrication environments.
FAQ's of Portable Rockwell Hardness Tester Model HR-150A:
Q: How does the Portable Rockwell Hardness Tester HR-150A operate without electricity?
A: The HR-150A features a fully manual control mode, utilizing levers and weights to apply the required test forces. This allows for immediate and precise hardness measurements independent of power sources, making it ideal for field or workshop use.
Q: What types of indenters are included with this model and when should each be used?
A: The HR-150A comes with both a diamond cone indenter and a 1/16" steel ball indenter. Use the diamond cone for harder materials (HRC, HRA scales) and the steel ball for softer metals (HRB scale), selecting based on the hardness range and material type being tested.
Q: Where is the HR-150A hardness tester ideally used?
A: This tester is suitable for on-site metal hardness testing, as well as applications in production workshops, laboratories, and quality assurance departments. Its durable and portable design makes it especially useful where mobility and flexibility are required.
Q: What is the process for performing a Rockwell hardness test with this unit?
A: First, select the appropriate indenter and test force according to the Rockwell scale required. Place the specimen on the anvil, apply the preliminary force, then the total force. The hardness value is displayed immediately on the dial indicator once the process is completed.
Q: What are the primary benefits of using the HR-150A model?
A: Key benefits include portability, ease of operation, high accuracy (ISO 6508/ASTM E18 compliance), immediate response time, and the capability to test large or heavy workpieces directly, reducing the need for sample cutting or preparation.
Q: How accurate is the tester and how is compliance ensured?
A: The HR-150A provides high accuracy with a resolution of 0.5 HR, strictly following the international ISO 6508 and ASTM E18 testing standards, ensuring reliable and repeatable results for every measurement.
