Product Description
The HR-150DTS Digital Electric Rockwell Hardness Tester features a fully automated loading and unloading system for reliable and consistent hardness measurement.
It eliminates manual zero adjustment — results are displayed directly on the digital screen with 0.1 resolution for fast and accurate readings.
This model supports automatic hardness conversion between HV, HB, and HR scales, extending its usability across multiple material types.
Its cast aluminum housing, made through a one-piece sand-casting process, provides excellent rigidity and stability, suitable for long-term industrial use.
The instrument operates with a 3.7V lithium battery and requires minimal power, offering extended operation time and built-in data output for connection with a printer or PC.
Compliant with ASTM E18 and ISO 6508 international standards, the HR-150DTS ensures consistent results for workshop and laboratory applications.
