Equipped with a digital display micrometer eyepiece with Japanese Omron encoder and a data calculation system accurate to 0.01μm, the hardness value can be accurately displayed with just one click
The main components adopt American 3M, Allegro, Japanese NKK, Omron and other brands to ensure long-term stable operation of the equipment
The lifting system protected by the national patent can realize 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 has HV2 hardness scale, which can be expanded to 2KG test force for testing; automatically input the length of the diagonal line, and can realize dual display of any hardness unit, intuitively judging whether the workpiece is qualified
The industrial LCD screen displays the material hardness value and various conversion hardness values, diagonal length, test method, test force, dwell time, measurement times, ambient temperature, maximum test value, minimum test value, average value, and repetition in real time on the industrial LCD screen The test process is intuitive and clear; the built-in printer can print out the data such as the number of measurements, hardness value, average value, maximum value, minimum value, and range for customers to file.
It is 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 parts replacement and maintenance and upgrading services.
