Product Description

The Rockwell Hardness Tester LRHT-A11 is a precision instrument for testing materials using HR15N to HR45TW scales. It features an initial load of 3 kgf (29.42N) with a 0–60 second dwell time and a 0.1 HR resolution, ensuring accurate results with an error margin of less than 1.0%. It uses electric loading with weights and a high-precision sensor for accurate measurements. It features automatic correction for high, medium, and low hardness values, along with built-in correction for convex cylindrical surfaces. The tester stores, processes, and automatically prints test results, making it efficient and easy to use.

Applications:

The Rockwell Hardness Tester LRHT-A11 is used for accurately testing the hardness of ferrous, non-ferrous, and plastic materials on the Rockwell scale. It is widely applied in quality control for manufacturing, metal processing, and material research.
