Product Description
The XHRS-150A Digital Plastic and Metal Rockwell Hardness Tester features an advanced optical grating sensor and computer-controlled measurement system.
It automatically displays hardness values on an LCD screen with 0.1 HR precision, supporting automatic conversion between multiple hardness scales.
The system identifies sample thickness and detects environmental temperature in real time, ensuring consistent and accurate readings.
An integrated printer allows users to record results instantly, minimizing manual input and human error.
The housing is cast in one piece using a special sand-casting process, providing rigidity, stability, and long-term dimensional accuracy.
The automotive-grade enamel coating offers excellent scratch and corrosion resistance, maintaining a polished finish for years.
It is suitable for both plastic and metallic materials, including soft metals, alloys, and rubber-like composites, in compliance with ASTM and ISO international standards.
