Precision and Versatility in Hardness Measurement

This digital hardness tester utilizes both diamond cone and steel ball indenters to deliver accurate Rockwell and Superficial Rockwell hardness values across multiple scales (HRB, HRC, HR15N/T/W, HR30T/W, HR45T/W). Its high-resolution LCD display and automated loading/unloading streamline the testing process for consistent and repeatable results.

Robust Design and User-Focused Operation

Equipped with overload and overtravel protection, this tester ensures the safety of both operator and equipment. The large worktable and test width accommodate various specimen sizes, enabling flexible use in diverse laboratory and industrial environments. The included accessories kit supports immediate use and maintenance.

FAQs of Digital Rockwell & Superficial Hardness Tester:

Q: How does the Digital Rockwell & Superficial Hardness Tester operate for different hardness scales?

A: The tester utilizes diamond cone and steel ball indenters along with selectable loading forces (15kgf-150kgf), automatically applying the appropriate load and measuring the hardness on Rockwell (HRB, HRC) and Superficial (HR15N/T/W, HR30T/W, HR45T/W) scales, all controlled via the digital interface.

Q: What types of specimens and maximum sizes can be tested with this machine?

A: Single specimen tests are supported, with a maximum height of 230 mm and depth of 150 mm, making it suitable for a wide range of metal samples commonly found in metallurgy labs and quality control settings.

Q: When is it beneficial to use the digital memory and result storage feature?

A: The memory function, which stores up to 50 test results, proves useful for batch testing, data tracking, and maintaining records for quality assurance or further analysis in laboratory and industrial applications.

Q: Where can the tester be installed and operated effectively?

A: With its bench/table top mounting design and manageable 80 kg weight, the tester is well suited for use in laboratories, workshops, and production facilities. It requires a 220V AC, 50Hz power supply for operation.

Q: What is the process for conducting a hardness test using this equipment?

A: Place the prepared specimen on the large table, select the desired test scale and load digitally, and let the machine automatically apply the force and perform the measurement. Results are shown on the LCD display within one second.

Q: How does the overload and overtravel protection benefit the operator?

A: These safety features prevent machine damage and ensure test accuracy by protecting the tester and specimen from excessive force or movement during use, adding reliability and extending equipment lifespan.
