Mitech MHRS-150 Digital Rockwell

Mitech MHRS-150 Digital Rockwell Hardness Tester

Product Overview

The Mitech MHRS-150 is a digital Rockwell hardness tester designed for high-accuracy testing of both metallic and non-metallic materials. It works based on the mechanical principle of pressing a diamond or hard alloy indenter into the surface of the test material and measuring the resulting indentation depth to determine hardness.

Equipped with an intuitive LCD screen and a built-in high-speed thermal printer, the MHRS-150 is ideal for batch testing in manufacturing environments, quality control labs, and educational or research institutions. It supports a wide range of Rockwell scales and is suitable for testing materials such as cast iron, steel, and soft alloys.

Key Features

• Large LCD display for clear visualization of test results and menu navigation

• Built-in thermal printer for instant printing of test reports

• High-quality diamond indenter for precise and durable measurements

• Grating displacement sensor minimizes indentation depth measurement error

• Error correction function improves measurement accuracy with button-based adjustment

• Hardness scale conversion between Rockwell, Brinell, and Vickers

• Automatic threshold alarm ideal for batch inspection of finished or semi-finished products

• Real-time environmental temperature monitoring for stable and reliable readings

• Supports 15 Rockwell test scales for compatibility with various test forces and indenters

• Fully compliant with EN-ISO-6508, GB/T230.1, GB/T230.2, JJG112, ASTM E18 international standards
