1 ULTRASONIC THICKNESS GAUGE BASIC LD7015
Ultrasonic thickness gauge specically designed to measure the thickness of metallic and non-
metallic materials e.g. aluminium, titanium, plastics, ceramics, glass and plastics. It can also be
used to monitor all types of pipes and pressure vessels for loss of thickness due to corrosion or
erosion. The gauge is easy to use and will give accurate readings to an accuracy of 1%. This unit is
not suitable for cast iron due to its big crystalloid composition.

Measuring range : 1.20 - 220 mm (steel); (deviation possible with use of
other materials)

• Ultrasonic thickness gauge basic
• Ultrasonic gel 60ml
• Transducer 10mm - 5.0MHz
• Calibration block
3 OPERATION INSTRUCTIONS
• Operation area condition: This gauge can measure all samples which are equal to or bigger
than the transducers surface area.
• Curved surface condition: When materials have a curved surfaces like a boiler wall or tubing,
the curvature radius must be equal to or more than 10mm and the wall thickness must be
equal to or more than 3mm.
• Roughness condition: This gauge is applicable for a wide range of materials. In most cases
the supplied transducer makes very accurate readings. However if the roughness is too big
due to rust etc. an error may occur. In this case please try to minimise the roughness or select
the 2.5MHz transducer. If the transducer is worn-out, please contact your local distributor for a
replacement transducer
• Working temperature condition: Material and sound velocity will change along with
temperature. In normal measurement conditions environment temperature impact can be
ignored. The transducer is made of propylene material. Considering the protection of the
transducer and its precision we recommend a surface temperature of the work piece should
not be over 60oC otherwise the transducer could be damaged.
• Operation temperature: 0 - 40oC
• Relative humidity: <90% RH
• Hardware / Work piece/ Material temperature: < 60oC
• Do not apply on vibrating or erosive material
• Avoid impact and moisture

4 PREPARATIONS
1. Switching on the instrument
Connect the probe to the main unit, press ON/OFF to
turn on the instrument. All display signs will light up for
0.5 sec on the LCD screen. Then it will show a value of
0.0mm and 5900 VEL and after that the last registered
sound velocity with selected memory unit. The instru-
ment is now ready for use.
2. Material selection
To select a material please press the VEL button several times to your needed material sign
appears as per below schedule:
Code Material Sound Velocity (VEL)
FS Iron/Steel 5900
AL Aluminium 6320
CP Copper 4700
bR Brass 4430
Zn Zinc 4170
TIN Tin 3320
Pb Lead (Pb) 2400
GL Glass / Stainless Steel 5800
PVC Polyvinylchloride 2390
PMM Acrylic 2730
3. Calibration
If necessary this step should be repeated; Press the“ZERO” key for 2 seconds, after a short time
“CAL”will appear on the display, this indicates the unit is in calibration mode. Put a small amount
of coupling gel on the sample block and then place the probe on the sample block. When the
display shows 4.0mm the calibration is completed. After calibration the sound velocity will
remain the same as previous selected. A calibration should be made the every time the probe or
batteries are replaced. This is very important to make sure measurements will be accurate.

5 PERFORM A MEASUREMENT
5.1 Thickness measurement
Put some coupling gel on the material surface, press the ultrasonic probe on the material surface
to measure. Please make sure there is good coupling, which will be indicated with this symbol
appearing on the display.
If this symbol does not appear or ashes it means there is not a good coupling. The reading on
the display is the measured value. After removing the probe, the reading will be held.
5.2 LCD backlight
By pressing this button you will activate the LCD backlight. With each operation the light
will switch on for about 7 seconds. When switching o the gauge the light will also automatically
switch o.

5.3 Automatic power shut down
If the instrument is not operated for over 2 minutes it will automatically switch o.
6 CALIBRATIONS
We recommend annual calibration. For calibration, send the instrument, together with a RMA
form* to TQC Sheen, Molenbaan 19, 2908 LL Capelle aan den IJssel, NL.
*You can download the RMA form here: https://www.tqc.eu/en/service/repairs-calibrations/
6 REPLACING BATTERIES
When the icon ashes, please replace the batteries before taking any new measurements.
Turn the instrument o by pressing the ON/OFF button. Open the battery lid and replace them
with 3 pcs of AAA alkaline batteries.
7 MAINTENANCE
• Though robust in design, this instrument is precision-machined. Never drop it or knock it over
• Always clean the instrument after use.
• Clean the instrument using a soft dry cloth. Never clean the instrument by any mechanical
means such as a wire brush or abrasive paper. This may cause, just like the use of aggressive
cleaning agents, permanent damage.
• Do not use compressed air to clean the instrument.
• Always keep the instrument in its case when not in use.
• We recommend annual calibration

1 ULTRASONIC THICKNESS GAUGE PRO LD7016
Ultrasonic thickness gauge specically designed to measure the thickness of metallic and non-
metallic materials e.g. aluminium, titanium, plastics, ceramics, glass and plastics. It can also be
used to monitor all types of pipes and pressure vessels for loss of thickness due to corrosion or
erosion. The gauge is easy to use and, after a simple calibration to a known thickness or sound
velocity, the gauge will give accurate readings to an accuracy of 1%. This unit is not suitable for
cast iron due to its big crystalloid composition.
