Dolphin Nose Rockwell & Superficial Hardness Tester (Model: DNRS-150NT)

The Dolphin Nose Rockwell & Superficial Hardness Tester (Model: DNRS-150NT) is an advanced, high-precision testing system engineered for ultimate permanent stability and exceptional ease of use. It features a unique, extended dolphin nose design that provides a generous vertical test height of 300mm and a deep throat depth of 220mm, allowing for the effortless evaluation of various components. Utilizing a manual handwheel for pre-loading, the machine fully automates the main-load application and the overall testing cycle. Instead of relying on traditional, cumbersome dead weights, the DNRS-150NT applies test forces via an innovative closed-loop control unit equipped with a high-accuracy load cell, a DC motor, and an electronic measurement and control unit. This cutting-edge setup guarantees highly precise and reliable measurements across all test loads with an impressive accuracy of up to 0.5%.

Designed to optimize modern industrial workflows, this model incorporates simple plug-and-play technology that makes its initial installation significantly quicker and easier compared to conventional weight-type machines. Structurally, the tester is built around a heavy-duty, integrated casting body with a wider basement to ensure permanent structural stability and minimize vibration during operation. To facilitate seamless data management and digital reporting, the DNRS-150NT comes fully equipped with integrated RS232 and USB ports for direct, hassle-free connectivity to a PC.
