Rockwell 574 Series Hardness Testers
The Rockwell® 574 Hardness Tester is a proven, durable, and reliable deadweight testing instrument. This system is available in Regular, Superficial or Twin Scale models and capable of testing in all of the regular Rockwell hardness scales (60, 100, and 150 kg major test forces), superficial Rockwell hardness scales (15, 30, and 45 kgf major test forces) and can accommodate a wide variety of applications. The Rockwell 574 Hardness Tester includes a rugged industrial design, a brand new user-friendly LCD panel, and a built-in USB port for rapid data transfer to Microsoft® Excel® or other applications. All Rockwell 574 Series Hardness Testers are equipped with a powerful auto-braking system on preload ensuring seamless operation, as well as a high-precision depth measurement system for accurate and repeatable testing. The 574 Series Rockwell Hardness Testers offer quality, durability, and an industry leading Gauge Repeatability and Reproducibility (GR&R) making this hardness testing instrument best in class.
