The KD-320 portable Leeb hardness tester can directly measure Rockwell (HRC, HRB), Leeb (HL), Brinell (HB), Vickers (HV), and Shore (HS) hardness values. Compliant with international standards and the 'Technical Conditions for Leeb Hardness Tester ZBN7100-1990' issued by the Ministry of Machinery Industry, as well as the 'Metallic Leeb Hardness Test Method GB/T 17394-1998' and Leeb Hardness Tester Standard JB/T9378-2001 issued by the State Administration for Quality and Technical Supervision. KD-320 can be equipped with 7 different types of impact devices on a single host, automatically identifying the type of impact device and eliminating the need for recalibration during replacement. Ultra low power consumption design, using high-performance lithium batteries to achieve ultra long working and standby time, and a more compact and flexible appearance design to improve usage flexibility. According to the principle of Leeb hardness measurement, high-precision testing can be performed on various metal materials. Supporting "Steel" materials, when testing "Steel" specimens with D/DC type impact devices, the HB value can be directly read without the need for manual table lookup. Convenient switching to all hardness standards (HL, HB, HRB, HRC, HRA, HV, HS), parallel conversion of various hardness measurement values. Functional features:
Display: Full Chinese display, menu style operation, simple and convenient operation. White backlit display, convenient for use in dark environments.
Data communication: equipped with USB interface, multiple communication methods to meet the individual needs of different users.
Measurement function: One host can be equipped with 7 different impact devices for use, and there is no need to recalibrate when replacing, automatically identifying the type of impact device.
Data storage: It can store 48-350 sets (32-1 impact times) of single measurement values, average values, measurement dates, impact directions, times, materials, hardness systems, and other information.
Alarm output: 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.
Calibration: Equipped with software calibration function for indication.
Battery: Built in high-performance lithium battery and charging control circuit, with ultra long working and standby time. The LCD displays the battery indicator and shows the current remaining battery level in real-time.
Software: According to user requirements, microcomputer software can be equipped with more powerful functions to meet higher requirements for quality assurance activities and management.
