Hardness Testing Perfected: ASTM & ISO Certified Results On-Site
Upgrade to the PHBR-300 automatic magnetic Brinell & Rockwell hardness tester — the smarter way to verify material hardness in the field. This revolutionary automatic magnetic Brinell & Rockwell hardness tester combines the reliability of desktop hardness testing with the magnetic Brinell & Rockwell methodology, delivering ASTM E10, ASTM E18, ASTM E110, ISO6506, and ISO6508 compliant results directly at your worksite.
Engineered for demanding field applications, the PHBR-300 automatic magnetic Brinell & Rockwell hardness tester effortlessly handles pipes, pipe fittings, bars, plates, large castings, forgings, shafts, molds and other large heat treatment parts of the field hardness testing.
Easy to Operate: After the PHBR-300 automatic magnetic Brinell & Rockwell hardness tester is fixed on the workpiece, the one-key operation can automatically complete the loading, maintenance and unloading of the test force, saving time and effort and good stability.
Accurate and Reliable: With its high-precision force sensor, the PHBR-300 automatic magnetic Brinell & Rockwell hardness tester employs advanced closed-loop measurement control technology to deliver accurate and reliable test force values, maintaining excellent consistency.
Real-time Monitoring: The OLED display on the PHBR-300 automatic magnetic Brinell & Rockwell hardness tester can display the status of the test step and the real-time test force value, which is convenient for the operator to monitor the application process.
