Ultrasonic Thickness Gauge Live A&B Scan Single & Dual
Element Probe
TG-4900DL ultrasonic thickness gauge developed and produced by HUATEC Group adopts OLED color screen
,which has the functions of built-in A-scan snapshot and B-scan
thickness function,thickness measurement through coating, large
capacity data storage and so on. Based on the principle of
ultrasonic measurement, it is a portable industrial nondestructive
testing instrument with high precision and high resolution.
The instrument can be widely used in manufacturing, metal
processing, chemical industry, commodity inspection and other
testing fields. In addition to accurately measuring all kinds of
plates and processed parts, it can also monitor all kinds of pipes
and pressure vessels in production equipment to monitor their
thinning degree after corrosion in the process of use. It is a
necessary instrument in the nondestructive testing industry.
All models of this series of instruments are equipped with A-scan
snapshot function as standard, which can help users better control
the measurement and avoid
wrong measurement caused by the factors of the material itself.
This thickness gauge has the function of measuring through the
coating: when there is a coating or paint layer on the surface of
the measured material, the actual thickness of the workpiece
substrate can be obtained without grinding and damaging the surface
coating of the workpiece.

Product Features - English language interface is optional
- Supports two thickness units: mm and inch
- Supports scheduled automatic shutdown and standby sleep
- The brightness of the screen can be adjusted to adapt to different
measurement environments
- When the probe is coupled with workpiece,the thickness value is
displayed in white font
- Extreme value mode: capture the maximum and minimum value during
the measurement process
- Large capacity data storage function: it can store 90000 thickness
values(optional)
- It can penetrate the coating on the surface of the workpiece and
directly measure the substrate thickness of the workpiece
(optional)
- Auto-Gain and Auto-Gate: The automatic measurement echo is
displayed on the A-scan interface
- When the measured value changes from green to white, it will be
accompanied by a buzzer tone
- Thickness alarm: the alarm thickness limit can be set, and the
thickness reading color can be changed dynamically during alarm
- B-scan thickness function: The user can directly observe the change
of the thickness of the workpiece with time on the screen
- Difference mode: obtain the difference between the current measured
thickness and the nominal thickness and the percentage between the
difference and the nominal thickness
- User-selectable measurement resolution: X.XXX, X.XX and X.X in
metric, X.XXXX, X.XXX and X.XX in imperial
- A-scan snapshot function: The users can directly see ultrasonic
signal waveform on the screen to verify whether the thickness
reading is correct,analyse the cause of the problem and help users
find a solution to the problem
