Description
The DigiRock TR7 is a premium fully automatic Twin Rockwell hardness tester designed for advanced laboratories, automated quality control environments, aerospace, automotive, and high-throughput manufacturing applications.
Unlike traditional Rockwell testers, the TR7 features a fully automatic moving-head design with closed-loop load control, delivering exceptional repeatability, reduced operator influence, and fast automated testing performance.
The fixed-stage construction improves testing stability and minimizes alignment errors commonly found in conventional screw-lift systems. Combined with high-speed precision motion control, the DigiRock TR7 is ideal for demanding production QC and statistical hardness analysis applications.
Featuring a high-definition LCD touch screen, automatic loading system, integrated data management, Bluetooth, USB and RS-232 connectivity, the TR7 is built for modern Industry 4.0 inspection environments.
