The Automatic Magnetic Rockwell Hardness Tester 300 applies the traditional Rockwell hardness test method, similar to table hardness testers. Designed to provide accurate and reliable measurements with ease, this tester utilizes a magnetic sucking disc to secure itself on large steel workpieces. The one-key operation simplifies the testing process, making it ideal for various steel materials including tubes, pipe fittings, bars, plates, as well as large heat-treated parts like shafts and molds.

Updated Structural Design: The compact and well-designed structure of the PHR-300 makes it smaller and lighter compared to the PHR-200, enhancing portability and ease of use.

Simple Operation: With a magnetic switch for attachment and one-key operation for testing, it offers user-friendly and stable performance.

High Accuracy: Features high accuracy force transducers, advanced closed-loop measurement, and control motor loading technology to ensure precise and reliable test results
