Common Functions:
The TKG Series of ultrasonic thickness gauges are compact, rugged devices
that use ultrasonic technology to perform non-destructive thickness
measurements on a variety of engineered materials. The most common
application is to detect corrosion and buildup in steel structures in which
only one side is accessible to take inspection measurements Designed and
made in the USA, TKG gauges are often used to inspect steam lines, boiler
tubes, storage tanks, and pressure vessels. These gauges are also used to
inspect marine systems, heavy equipment, aircraft sections, and bridge
structures.
Rugged and Versatile:
Designed for use in harsh conditions, TKG gauges are made of an
impact-resistant material. All three models are IP54-rated for dust and water
resistance and are ideal for quality control applications beyond metals,
including castings, plastics, composites, fiberglass, ceramics, and glass. The
TKG-150 and TKG-250 models have added versatility with Vibration Alerts,
an Echo-to-Echo measurement mode that ignores paint and coatings, and
Automatic Datalogging.
Ergonomic and Intuitive:
Some of the key advantages of the
TKG Series include its intuitive interface,
easy-to-read display, and various alarm
modes. These innovations make it easier
to use the device’s advanced functions,
such as the user-configurable Fast
Minimum/Maximum threshold settings,
which, combined with unique
Vibration feedback alerts and various
Visual alarms, help reduce the likelihood
of missing critical thickness parameters,
even by new users.
Clear and Bright Display:
Readable in bright sunlight, the
on-screen data displays filename, ID
number, thickness measurement,
minimum threshold, gain, rectify and
range settings, and the three menu items
on the bottom of the screen correspond
to the F1 – F2 – F3 buttons. The battery
% level is always visible on screen, and
the TKG gauges provide an extended
battery life from two AA batteries. (See

TKG-KIT
All models include 2oz bottle of couplant, 2 AA batteries, Transducer (5MHz,
0.375” diameter ) with potted cable, and hard case. TKG-150 and TKG-250
also include protective holster, USB cable, and XPorter software.
How the Technology Works:
The Dual-Element Transducer (see illustration)
employed in the TKG Series creates an angular
sound path (referred to as a “roof angle”) that
captures thickness readings in a wide range of
engineered materials.
Using this measurement technology, the
TKG-Series is especially adept at detecting
corrosion and buildup within steel structures.

Gain - Variable adjustment
-
Low, Standard, High In 1dB steps from 20-90dB or Automatic Gain
Control (AGC) for waveform
B-Scan - (Non-Encoded)
-
Displays a visual cross section of inspection area with no correlation to
distance. B-Scan alarm colors consist of: Red = below minimum/above
maximum; Yellow = Caution; and Green = Good.
Echo-to-Echo
-
Measure the metal thickness only (paint & coatings do not affect base
material thickness value)
Differential Mode
-
Displays the difference from the actual thickness measurement and a
user entered reference value
Velocity Mode
-
Displays acoustic sound speed to measure thicknesses of unknown
materials
Datalogger
-
Stores 50,000 readings (expandable to 100,000) and 5,000 waveforms;
file names up to 20 charac-ters long; and the included Extech XPorter
software extracts .csv data files that can be opened for viewing in MS
Excel, Notepad, or Wordpad. TKG250 also has file compare and grid
review features.
