Overview of Fangyuan FY310 Portable Rockwell Hardness Tester:

The Fangyuan FY310 portable Rockwell hardness tester, based on the principle of Leeb hardness measurement, can conveniently and quickly measure various metal materials. While displaying the hardness measurement value immediately, it can freely switch between multiple hardness systems (Brinell HB, Rockwell HRC, Vickers HV, Shore HS), pre-set tolerance limits, and automatically alarm when exceeding the range. The host of this product is designed to be integrated with a high-speed thermal micro printer. The original imported high-speed printer core supports on-site instant printing function, and the imported long-lasting printing paper ensures long-term data storage. The low-power design concept relies on stable IC integrated circuits and comes standard with high-capacity, long-life, high-speed charging nickel hydrogen battery packs. Full Chinese display, menu based operation is simple and convenient, and seven types of irregular impact devices do not require calibration and are automatically recognized. It is your best choice for hardness testing.

5. It can store up to 100 sets of hardness measurement data (impact frequency 32-1), each set of data including single measurement value, average value, measurement date, impact direction, frequency, material, hardness system, and other information.
6. The thermal printer is integrated with the instrument, which works quietly, has fast printing speed, and can print inspection reports on site.
7. Built in nickel hydrogen rechargeable battery and charging control circuit; Can work continuously for no less than 150 hours; It has energy-saving functions such as automatic sleep mode and automatic shutdown.
8. There is a remaining battery indicator icon on the LCD, which can display the remaining battery level in real time; Equipped with charging process indicators, the operator can keep track of the charging level at any time.
9. It has a USB interface that allows for convenient and fast data exchange with a PC. It can be equipped with microcomputer software, which has rich functions such as transmitting measurement results, storing and managing measurement values, statistical analysis of measurement values, printing measurement reports, and batch setting instrument parameters, meeting higher requirements for quality assurance and management.

　　On site testing of portable hardness tester
1. After arriving at the site, the first thing to confirm is whether the temperature of the workpiece is at room temperature, because the working conditions of portable hardness testers are around 0-40 degrees. Some workpieces have just been annealed or cut, which cannot be detected immediately and can cause damage to the portable hardness tester and affect the hardness value. In the first two years, when our unit was conducting maintenance on a gas tank at a liquefied gas station, the weld seam had just been quenched and had not been completely cooled, so we immediately conducted a hardness test. However, the portable hardness tester was not tested twice, and the data was messy.
2. The environment around the workpiece should be checked for strong magnetic fields, corrosive media, vibration strikes, and dust flying, all of which are not conducive to hardness testing. For example, in terms of vibration, if you measure it here and he hits the workpiece on the other end, the hardness values produced will vary and be inaccurate. Corrosive media and dust can cause damage to portable hardness testers. If it were a metal casing, these factors could be avoided.
3. Due to the presence of oil stains, oxide scales, turning or cold working on the surface of the test part of the workpiece, it needs to be polished and cleaned. The tested surface should be exposed to a metallic luster, smooth and even. Polishing tools can generally be angular polishing machines (hand grinders), flat files, or sandpaper. Surface treatment is very important, and if not done properly, it can affect the hardness data. Therefore, you can generally use an angle grinder to grind it quickly. After grinding, you can use sandpaper to lightly polish it, which is easy to operate. 4. Start the test, select the corresponding material for the portable hardness tester based on the material of the workpiece being tested, and then choose the number of measurements. Nowadays, it is usually measured at three points on one test surface. Choose a hardness system, whether it is Brinell, Rockwell, Vickers, or Leeb, and also choose the direction of hardness impact.
4. The choice of impact direction for hardness is crucial. The hardness values measured in different directions are different. Sometimes, when we test in different directions, we forget to choose the direction on the portable hardness tester, resulting in deviation in hardness values. However, the portable hardness tester shows that there has been no change, and the results can be imagined, so this should be particularly noted during on-site hardness testing.
5. After the hardness test is completed, the power should be immediately turned off, then the impact device should be removed, wiped clean with a soft cloth, and stored away. At this point, you can also charge the portable hardness tester based on its power consumption display, ensuring sufficient battery power every time it is used.
