Universal hardness tester (digital display)

Universal hardness tester(Digital Display)HBRV(M)-187.5Equipped with an intuitive LCD screen display and microcontroller control system, the hardness testing has been automated. The machine has a built-in printer that records the main technical data throughout the entire testing process. In addition to manual lifting of the test bench, automated operations such as applying and removing test force, and direct display of hardness values have been achieved. This machine has high testing accuracy and eliminates human operation errors.
