Digital Micro Hardness Tester, Automatic Turret Switching (CAT#: STEM-DTE-0073-YJL)

Digital Micro Hardness Tester, Automatic Turret Switching, model HVD-1000AP is manufactured by Shanghai Jvjing Precision Instrument Manufacturing Co., Ltd. Compared with ordinary models, the digital display microhardness tester has improved the test speed, and can directly display the hardness value without manually inputting the length of the diagonal line. This machine adopts imported components to ensure more stable operation of the equipment, and the lifting system protected by the national patent is applied. The upgraded control system can provide more measurement data, and the control is more comprehensive and accurate.

Optional parts: hardness measurement software, metallographic equipment, Knoop indenter, standard hardness block, 15X micrometer eyepiece

Equipped with a digital display micrometer eyepiece and a data calculation system accurate to 0.01μm, the hardness value can be directly 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 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 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, 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.
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 bright as new after many years of use
Our company has the ability of self-development, design, production and processing, and our machines provide life-long parts replacement and maintenance and upgrading services;
