601MHB type digital small load Brinell hardness tester (automatic turret)Detailed product description：

601MHB digital small load Brinell hardness tester (automatic turret)

The digital small load Brinell hardness tester is a high-tech product that integrates optics, electronics, and electronics. It has a novel and beautiful design, good intuitiveness, operability, and reliability, and is an ideal product for testing small load Brinell hardness.

The main functions of the 601MHB digital small load Brinell hardness tester (automatic turret) are:
1. This instrument has a 7-level testing force and allows for the selection of 8 different Brinell scales for testing;
2. Equipped with two sets of objective lenses, 5 ╳ and 10 ╳, both of which can participate in measurements;
3. Intelligent automatic switching between objective lens and pressure head;
4. Pre set test force holding time and adjust the strength of the measuring light source function;
5. Automatically display measurement indentation length, hardness value, measurement frequency, etc;
6. Print and output hardness test results, RS232 terminal settings for users to expand functionality.
7. The hardness tester can also be equipped with CCD devices, video measurement devices, and camera devices according to users' special needs.
8. This instrument adopts a precise structural design, and the application of test force is controlled by a force sensor, making the overall structure compact and ensuring smooth and accurate loading and unloading of test force. In terms of electrical control, the testing process is controlled by the CPU. The objective lens and indenter adopt intelligent automatic switching, and the switching positioning adopts mechanical and electronic dual cooperation to achieve higher positioning accuracy.
9. This instrument is suitable for measuring cast iron, non-ferrous metals, and alloy materials, as well as various annealed and quenched and tempered steels. Especially for softer metals such as aluminum, lead, tin, etc., the hardness values tested are more accurate.
