THS141 roll special Leeb hardness tester
Model: THS141
THS141 roll special-purpose Leeb hardness tester is a professional measuring roll Leeb hardness tester with a measuring range (30～110) HSD. It is mainly suitable for testing the hardness of metal materials. It has high test accuracy, small size, easy operation, and convenient carrying. Features of wide measuring range. THS141 roll special-purpose Leeb hardness tester is based on Leeb's principle, and the measured Leeb (HL) hardness value is automatically converted into Brinell, Rockwell, Vickers, Shore and other hardness values through the program, and various tests can also be configured. Accessories, to meet various test conditions and environments, THS141 roll special Leeb hardness tester is mainly suitable for rapid testing of the hardness of metal materials, especially suitable for on-site hardness testing of large parts and non-detachable parts.
Features of THS141 roll special Leeb hardness tester:
1.Leeb and Shore for Roll can one-key conversion, the measuring range of Shore (30～110) HSD
2.Based on the Leeb hardness measurement principle, it can detect a variety of metal materials.
3.Large screen, 128×64 graphic dot matrix LCD display, rich in information, intuitive, and clear display. The screen brightness can be set freely according to the environment and light.
4.Built-in thermal printer, no noise, fast printing speed, can print test report on site.
5.One host can be equipped with 7 different impact devices, automatically recognize the type of impact device, and do not need to recalibrate when changing.
6.Full Chinese display, menu operation, simple and convenient measurement.
7.The USB interface can easily and quickly exchange data with the PC. Standard
microcomputer software, with rich functions such as transmission of measurement results, measurement value storage management, measurement value statistical analysis, printing measurement report, batch setting of instrument parameters, etc., to meet the higher requirements of quality assurance and management.
8.Up to 500 sets of hardness measurement data (number of impacts 1~32) can be stored, each set of data includes single measurement value, average value, measurement date, impact direction, number of times, material, hardness scale and other information.
9.Support "Steel" material, when using D/DC type impact device to test "Forged Steel" sample, the HB value can be read directly without manual check-up table.
10.The upper and lower limits of the hardness value can be set in advance, and the alarm will be automatically alarmed if the range is exceeded, which is convenient for the needs of users for batch testing.
11.With EL backlight display, it is convenient to use in dimly lit environments.
12.With software calibration function, users can calibrate the instrument by themselves.
13.Built-in Ni-MH rechargeable battery and charging control circuit; it can work continuously for no less than 150 hours; it has power saving functions such as automatic sleep and automatic shutdown.
14.There is a remaining battery indicator icon on the LCD, which can display the remaining battery power in real time; with a charging process indicator, the operator can know the charging level at any time.
15.Completely sealed shell, compact, portable, high reliability, suitable for harsh
16. operating environment, anti-vibration, shock and electromagnetic interference.
17.Dimensions: 212mm×80mm×32mm
