HLN160 Leeb hardness testerDetailed product description：

HLN160 Leeb Hardness Tester Product Features:

·It has a power on self-test function and factory parameter recovery function to ensure the normal operation of the system.
·It can automatically shut down in 5 minutes or work for a long time.
·Adopting two operation modes: direct mode and menu mode, the operation is flexible and convenient.
·Adopting a large screen dot matrix LCD, fully Chinese display, user-friendly interface, rich content, beautiful and clear text and graphics, not affected by voltage fluctuations.
·The main display interface can display content such as date, time, storage information, battery information, over limit prompt, impact device, direction, material, operation prompt, etc.
·All interfaces have prompts, which can be used to complete various operations.
·Large capacity storage, capable of storing 250 sets of data (up to 6500 single measurement values), each set of data including up to 26 single measurement values, average values, test dates, impact directions, materials, hardness, and other information. It can be saved for a long time for future browsing, editing, printing, and transmission.
·Equipped with a peak holding circuit, it has strong adaptability to various impact devices.
·The host can be equipped with 7 different impact devices, which automatically determine whether the impact device is connected properly and identify the type of impact device.
·It has dual functions of software calibration and hardware calibration, expanding the calibration range and ensuring testing accuracy. The impact device calibrated by software does not require recalibration when replaced.
·It can be automatically converted into HRC, HRB, HRA, HB, HV, HS, and δ b according to the type, direction, and material of the impact device.
·Automatically delete out of limit data, set upper and lower limits for hardness values, automatically determine whether the test data exceeds the upper limit, is qualified, or exceeds the lower limit, and achieve automatic inspection.
·The addition of "forged steel" material allows for direct reading of HB values when testing "forged steel" specimens using a D/DC impact device, eliminating the need for manual table lookup.
·It has a warning and alarm function, and special warnings have warning sentences on the display interface.
·Built in intelligent voltage management system ensures stable and reliable power supply voltage, avoiding circuit damage and LCD display abnormalities caused by high or low voltage.
·There is a battery level indicator, charging and charging completion prompt on the main display interface, with a charging indicator light, making it clear whether it is in charging state.
·The charging status instrument can work normally with an external power supply without affecting charging.
·There is a backlit display, making it convenient for users to use in low light conditions.
·The printer is integrated with the host, using a needle print head (suitable for long-term storage), fully printed in Chinese, and can print any group and any number of test results at will.
·Equipped with RS232 interface, it can transmit all measured data to the microcomputer for easy management.
·There is a service information window that prompts users for the address, phone number, and contact person of the after-sales service center of this instrument, in order to provide users with high-quality service.
