Chengdu THVP-50 Digital Vickers hardness tester

I. Features: THVS Series Digital Vickers hardness tester instrument uses sophisticated design on the machine, the change in the value of the test force force reduction or increase in weight and changes to the sensor control, so that the whole structure more simple force value is more stable and accurate. Electrically controlled testing process by the CPU, the introduction of new technologies in optical high-resolution optical measurement systems, optical sensing and cold light source. Operated by the soft input panel can preset test force dwell time, select Vickers or Knoop test method, adjust the strength of measuring light sources and other functions. And can measure the length of indentation display on the LCD screen liquid, hardness value, test force dwell time, number of measurements and the like. THVP series of large-screen Digital Vickers hardness tester 1, Digital Vickers hardness tester series is electromechanical integration of high-tech products, using a large LCD display screen, it is clean, beautiful, with good intuition, can operability and reliability, making it ideal for testing Vickers hardness. Conversion of the aircraft between the indenter and objective lens with automatic switching device. 2, hardness using mechanically sophisticated design, using high-magnification lens and digital display micrometer eyepiece is optically measured using cold light source other advanced technologies. 3, the use of closed-loop load control system, improve the accuracy of the test force, good reproducibility and stability of the indicated value. The system is used on the Vickers hardness tester, first in the country. 4, operated by a touch key input on the front panel, can preset test force dwell time, adjust the strength of measuring light sources and choose the Vickers or Knoop test mode, the hardness scale conversion, document number and storage. And can be displayed on a screen measuring indentation length, hardness value, number of measurements and the year, month, day and time, etc., test results and data processing, and output through the printer, as well as connect to the computer via an RS232 interface. You can also configure the above hardness CCD device, screen means and the imaging device according to the special requirements. Suitable for measuring small, thin specimen, surface infiltration and microscopic parts of agate, glass, ceramics and other brittle materials after plating treatment and Knoop hardness measurement and coating, surface coating, laminated metal, heat carbonization Determination of the depth and hardness gradient layer and hardened layer. For research institutes, factories and QC departments, research and testing of ideal hardness testing equipment.
