Digital Rockwell Hardness Tester - Rocky D-150 Features

	Uses a motorized system to control the application and release of test force, effectively minimizing errors.
	Built-in printer for instant data output and recordkeeping.
	Supports ASTM E140-12be, ISO 18265:2013 hardness conversion standards. Automatically converts hardness values—eliminating the need to consult complex comparison tables and saving valuable time.
	The system includes single-point and multi-point modes. In multi-point mode, it provides hardness distribution curve analysis and automatically calculates the maximum, minimum, and average values, making it easy for users to analyze the test data.
	By setting upper and lower hardness limits, the system can automatically trigger a pop-up window, notifying the user whether to save and print the test results.
	15 measuring scales can be independently customized.
	User-friendly interface with easy operation. Equipped with an integrated data processing and display system powered by a dual-core 32-bit ARM processor.
