Ultrasonic Thickness Gauge |
 |
 Transducer |
The TKG Series Thickness Gauges, designed in
compact, handheld, rugged housing are 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. |

English, French, Spanish, Italian, Czech, German, Portuguese, Slovak,
Finnish, and Hungarian |
| Hold Mode: |
Holds display to retain last thickness reading with reverse video display |
| Freeze Mode: |
Freezes display (ideal for high temperature readings) |
| Fast Min/Max Mode: |
Displays Min or Max and actual thickness value at 20 measurements/sec |

| 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 |
| Battery Life: |
Up to 50 hrs (20hrs w/ backlighting) |
8 to 14hrs (depends on operating conditions) |
