Features

l According to the Leeb hardness measurement principle, it can detect a variety of metal materials with high precision.

l Support "Steel" material, when testing "Forged Steel" specimens with D/DC impact device, the HB value can be read directly, without manual table checking.

l It is convenient to switch to all hardness systems (HL, HB, HRB, HRC, HRA, HV, HS) and convert the measured values of each hardness system in parallel.

l Large-screen 128×64 graphic dot matrix LCD display, rich in information and intuitive.

l Full Chinese display, menu-based operation, simple and convenient operation.

l Fully automatic backlight display, convenient to use in dark environments.

l RS232 communication interface, which can easily and quickly exchange data and set parameters with the PC.

l One main machine can be equipped with 7 different impact devices, and the type of impact device can be automatically identified. There is no need to recalibrate when replaced.

l It can store up to 600 sets of hardness measurement data (impact times 32~1). Each set of data includes information such as a single measurement, an average value, the date of measurement, the direction of impact, the number of times, the material, the hardness system, etc.

l The upper and lower limits of hardness value can be set in advance, and the automatic alarm will be given when the range is exceeded, which is convenient for the needs of users for batch testing.

l The power supply adopts 2 AA (No. 5) ordinary alkaline batteries, which can work continuously for no less than 150 hours, and has power-saving functions such as automatic sleep and automatic shutdown.

l There is a residual power indicator icon on the LCD, prompting the user to replace the battery in time.

l It has the function of calibration of the value indication software.

l It can be equipped with powerful microcomputer software, which has rich functions such as transmitting measurement results, measuring value storage management, measuring statistical analysis, printing measurement reports, etc., to meet the higher requirements of quality assurance activities and management.

l Design according to the standard: "Technical Conditions for Leeb Hardness Tester" JB/T 9378-2001.
