Digital Blovey Hardness Tester THBRVS-190

Features:

1.This hardness tester has a novel appearance, complete functions, convenient operation, clear and intuitive display, and stable performance. It is a high-tech product that integrates mechanical, electrical, and optical testing. It can be tested using three testing methods: Brinell, Rockwell, and Vickers.

2. The body part of the product is formed in one go through a casting process and has undergone long-term aging treatment. Compared to the panel assembly process, long-term use has minimal deformation and can effectively adapt to various harsh environments;

3. Automotive paint, with high quality and strong scratch resistance, remains shiny and new after years of use;

4. Ready to use upon startup, without the need to install weights;

It adopts a large screen touch LCD display interface, with rich display content and convenient operation;

5. The electronic closed-loop control applies the test force, with an accuracy of 5 ‰. The force sensor controls the test force, fully realizing the automatic operation of applying, maintaining, and removing the test force;

6. The hardness values of each scale can be converted to each other through measurement;

7. The body is equipped with a micrometer and a high-definition micro optical system to make the observation readings clearer and reduce errors;

8. Equipped with a built-in micro printer and optional RS232 data cable, it can be connected to the computer through a super terminal to export measurement reports.

9. Equipped with three testing methods of Brinell, Rockwell, and Vickers, with multi-level testing force, it can meet various hardness testing requirements;
