The Leeb hardness tester is a rapid hardness test method. The related technology of digital ultrasonic hardness testerhas made rapid progress in recent years. The measurement and accuracy of the Leeb hardness tester have been comparable to the international advanced technology. The pd-H series of Leeb hardness tester is developed paint hardness testerhas achieved a number of technological breakthroughs and performance optimization: 1. Built-in Bluetooth module, support for wireless printing, 2. LCD screen display with backlight, and adjustable contrast, suitable for various operating scenarios reading. 3, automatic shutdown time is adjustable, open more optimized power-saving mode 4, with self-learning system conversion 5, USB charging 6, it is to clear under voltage and charging instructions. 7.it is imported thermal printer head, print smooth, clear fonts. The development of hardness tester of metals is no less important than the international level. The export products have been greatly improved. The manufacturers have their own characteristics. The former homogenization phenomenon has been reduced, and the entire industry has shown a good trend.


First, pay attention to the use of the environment


Avoiding foreign matters such as iron filings, oxide scale, dust, etc. into the machine, which is causing a short circuit to burn the machine,hardness tester for soft materials is avoiding applications in places with strong electromagnetic interference, such as PHS antennas, high-frequency furnaces, causing abnormal operation of the instrument,which should be at working temperature In 0°C ~ 40°C, relative humidity≤ 90%, there is no direct sunlight, no vibration, no strong magnetic field, non-corrosive medium and severe dust environment.


Second, the requirements of the tested parts


The rubber shore hardness tester should pay attention to the requirements of the tested part during the use process to ensure that the surface of the test piece should be clean and free of dust, oil and oxide scales. The surface of the tested part can be partially polished with a grinder to show the metallic color. The surface temperature of the barcol hardness testing must not be too high and the temperature should be less than 120°C. The optimal temperature for testing is 4°C-38°C.


Third, analyzing the characteristics of the test specimen to be tested


The surface of the hardness tester for metalic material shall be smooth and the test piece shall not be magnetic. The material of the test shall correspond to the material preset by the instrument. The thickness of the test piece shall meet the test requirements.The external dimensions of the test piece shall be consistent with the support ring.


Fourth, testing the specimens


For medium and small specimens, portable hardness tester support or adhesive treatment must be performed. For special materials, comparative experiments are to be performed. Bench hardness testers with the same hardness test and comparison curves are made on the same test specimen to ensure accurate test accuracy.
