Ultrasonic hardness tester is composed of host, probe and probe
connection cable.
The probe is connected to the host with an eight-core connection
cable for signal transmission. The host adopts a color display with
rich display content.
There are nine buttons on the front of the host to operate.
A USB interface is on the side of the host for charging and
communication.
The charge lamp near the USB interface is used to indicate charging
status.
1.Main hardness scale: HV
Convertible hardness scale: HRC, HRA, HRB, HBW
2.In multi-points calibration mode, any hardness scales can be
chosen.
3.Testing range: HV50~1599, HRC20~68, HB85~650
4.Test direction:Support 360° test, as long as the angle between
the indenter and the surface doesn’t exceed 90° ± 3°.
5.Battery: 3.6V, 3000mAh lithium battery
6.Endurance: 10 hours
7.Test data can be exported to computer terminal.
8.Norms: DIN 50159-1-2008; ASTM-A1038-2005; JB/T 9377-2010;
JJG-654-2013;JJF 1436-2013.
10.Tiny test indentation---- requires a high-power microscope to
see.
11.Little damage to the workpiece.
12.High test speed----output test results in 1s at the soonest.
13.New appearance design, innovative sculpt, convenient to hold and
good craft.
14.Full English display, menu-type operation, few keys, simple and
convenient to operate.
15.inches large LCD screen with 320×480 color graphics dot matrix,
beautiful font and graphics, rich information and clear display.
16.Directly display the current measured value, cumulative measured
value, maximum value, minimum value, average value and conversion
value.
17.50 sets of data storage.
18.Simple calibration----5 sets of one-blockcalibration data, 1 set
of default calibration data and 5 sets of multi-blocksscalibration
data can be stored in the host.
19.For materials with different elastic constants, just anone-block
calibration is required to adapt to the new material.
20.For unknown material or material without conversion table, the
hardness scale can be arbitrarily selected for multi-points
calibration to eliminate the systematic error brought by the
conversion table.
21.Easy to test on assembly line.
