Description

Compact rugged meter for non-destructive thickness measurements

The TKG250 is a Digital Ultrasonic Thickness Gauge/Datalogger with Color Waveform function. 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. Datalogs up to 100K readings and can be exported to Excel® for further analysis. Complete with protective holster, 2oz bottle of coolant, 2 AA batteries, 5MHz Transducer, hard carrying case, USB cable and Exporter software.

Specifications Range
Steel Thickness Range 5MHz probe: 0.040 to 20″ (1.0 to 508mm); 10MHz probe: 0.030″ to 2″ (0.76mm to 50.8mm)
Material velocity calibration range 0.200 to 0.7362 in/μS (0.508 to 18.699mm/μS)
Languages 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
Units Inches/Millimeters/Microseconds
Alarms Audible beeping; illuminae flashing display and keypad; and vibration feedback
Illuminating Keypad F1 = Red, F2 = Yellow, F3 = Green for easy, go/no-go testing
Gain – Variable adjustment 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. File compare & grid review
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 8 to 14hrs (depends on operating conditions)
