Product Description
The HR-150DT Electric Rockwell Hardness Tester is a precision mechanical instrument designed for reliable hardness testing in industrial and laboratory environments.
It adopts an automatic loading and unloading system driven by a motorized mechanism, providing highly consistent test force and repeatable measurement results.
Hardness values are directly displayed through a sensitive dial gauge, ensuring fast, accurate, and stable readings.
The tester's body is made using a single-piece sand-casting process, maintaining long-term rigidity and deformation resistance.
Its surface is coated with automotive-grade enamel, resistant to scratches and corrosion, maintaining a bright appearance even after years of use.
This model combines mechanical precision with convenient operation, making it ideal for workshops, quality inspection, and laboratories.
Fully compliant with ASTM E18, ISO 6508, and EN 10109 international standards.
