Ultrasonic
Thickness Gauges
Extech offers Thickness Gauges designed in compact,
handheld, rugged housing ideal for field use. The
ultrasonic technology allows for non-destructive
thickness measurements for primarily steel structures.
Select models with digital thickness readout or live
color waveform and datalogging function.
Applications:
- Boiler Tubes
- Pressure Vessels
- Storage Tanks
- Ship Hulls
- Containers
- Home Oil Tanks
- Pipes
- Steam Lines
- Compressors
- Shafts
- Bridge Pins
- Bond Inspection

Additional Functions Model TKG100 Model TKG150 Model TKG250
Gain - Variable adjustment — Low, Standard, High In 1dB steps from 20-90dB or Automatic Gain Control (AGC) for waveform
B-Scan - Displays a cross
section of the test piece —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 thickness of unknown materials
Datalogger —
Stores 50k readings (expandable to 100k) and 5,000 waveforms; file names up to 20 characters
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 & grid review features.
Range — — Adjustment of manual range control or auto zoom tracking to center
echoes independent of selected range
Rectification Modes — — RF, Half Wave Positive, Half Wave Negative and Full Wave Rectification
Live Waveform (A-Scan) — —
Full adjustments for gain in 1dB step or AGC, main bang blank, blank after
first received echo, range including zoom auto tracking to center echoes
independent of material and rectification
