The main components adopt American 3M, Allegro, Japanese NKK, Omron and other brands to ensure long-term stable operation of the equipment
The self-developed lifting system can achieve easy focusing and more stable lifting; the proprietary ball positioning system repeats positioning more accurately, ensuring the accuracy and repeatability of the entire testing process
The optical system designed by our senior optical engineer not only meets the definition requirements of the hardness test, but also can be used as a simple microscope with adjustable brightness, clear image and comfortable vision, and it is not easy to be tired after long-term operation
This machine has Vickers hardness and Knoop hardness testing functions, and HV2 hardness scale can be expanded to 2KG test force for testing; by inputting the diagonal length of the indentation, the hardness value can be directly displayed, avoiding the tedious look-up table
The hardness value, converted hardness, test method, test force, dwell time, measurement times, and test process can be intuitively displayed on the industrial LCD screen; the built-in printer can record the measurement times, hardness value, average value, maximum value, and minimum value. Value, range and other data are printed out for customers to file.
Randomly equipped with data transmission software, which can transmit the measurement data of the host computer to the computer for editing and saving through the RS232 interface
The cast aluminum shell is formed at one time, the structure is stable and does not deform, the pure white car paint is of high grade, strong scratch resistance, and it is still as bright as new after many years of use
Our company has the ability of self-development, design, production and processing. Our machines provide life-long spare parts replacement and maintenance and upgrading services.
