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.

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
