Product Overview: Based on the principle of Leeb hardness measurement, the Fangyuan FY310 portable Leeb hardness tester can conveniently and quickly measure various metal materials. It can display the hardness measurement value immediately and can freely convert between multiple hardness systems (Brinell HB, Rockwell HRC, Vickers HV, Shore HS). It can pre-set tolerance limits and automatically sound an alarm if it exceeds 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. Functional features: 1. Based on the principle of Leeb hardness measurement, it can detect various metal materials; It has software calibration function. 2. One host can be equipped with 7 different impact devices for use, automatically identifying the type of impact device and eliminating the need for recalibration during replacement. 3. Support "Steel" materials. When testing "Steel" specimens with D/DC impact devices, the HB value can be directly read without the need for manual table lookup. 4. The upper and lower limits of the hardness value can be pre-set, and an automatic alarm will be triggered if it exceeds the range, which is convenient for users to test in batches. 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. 10.

The surface temperature of the specimen should not be too hot, and should be less than 120 ℃. 2. The surface roughness of the specimen should not be too large, otherwise it will cause measurement errors. The tested surface of the sample must show a metallic luster, and be flat, smooth, and free of oil stains. 3. Requirements for sample weight: For heavy samples weighing more than 5kg, no support is required; Specimens weighing between 2-5kg with overhanging parts and thin-walled specimens should be supported by objects during testing to avoid deformation, bending, and movement caused by impact forces. For medium-sized specimens, they must be placed on a flat and sturdy surface, and the specimens must be placed absolutely steadily without any shaking. 4. Curved specimen: The test surface of the specimen is preferably flat. When the curvature radius R of the tested surface is less than 30mm (D, DC, D+15, C, E, DL type impact devices) and less than 50mm (G-type impact devices), small or irregular support rings should be used during testing. 5. The sample should have sufficient thickness, and the minimum thickness of the sample should comply with the provisions of Appendix 3. For specimens with a surface hardening layer, the depth of the hardening layer should comply with the provisions of Appendix 3. 7. Coupling: For lightweight specimens, they must be tightly coupled with a sturdy support, and the two coupling surfaces must be flat and smooth. The amount of coupling agent used should not be too much, and the testing direction must be perpendicular to the coupling plane; When the specimen is a large-area plate, long rod, or bent part, even if the weight and thickness are large, it may still cause deformation and instability of the specimen, resulting in inaccurate test values. Therefore, reinforcement or support should be provided on the back of the test point. 8. The magnetic properties of the sample itself should be less than 30 Gauss.
