Product Description
The HRM-45DT Electric Superficial Rockwell Hardness Tester is a precision instrument that integrates automatic control and stable mechanical performance.
It adopts a motor-driven loading and unloading system, which guarantees test-force accuracy and eliminates operator influence.
Hardness values are read directly through the high-sensitivity dial indicator, providing rapid and repeatable measurement results.
The outer shell is produced by a one-piece sand-casting process, ensuring mechanical stability, rigidity, and long service life even in challenging environments.
The surface finish uses automotive-grade enamel, providing scratch resistance and maintaining a polished appearance for years.
Designed for workshop and laboratory applications, this model ensures consistent performance across steel, alloys, and hard-coated materials, in compliance with ASTM E18, ISO 6508, and EN 10109 international standards.
