Product Description
The HR-150AS Manual Digital Rockwell Hardness Tester is a classic, reliable testing instrument suitable for industrial and laboratory use.
It adopts a mechanical manual loading system, requiring no external power supply, making it ideal for stable, efficient operation in varied environments.
The hardness value can be read directly on the digital display, with a resolution of 0.1 HR, and supports conversion to Vickers (HV) and Brinell (HB) hardness units.
Its cast body is made through a one-piece sand-casting process, ensuring long-term stability and high resistance to deformation.
The surface uses automotive-grade baked enamel, providing excellent scratch resistance and a glossy finish even after years of use.
This model combines the traditional mechanical system's simplicity with modern digital precision, making it both economical and reliable for daily hardness testing.
