TKG150 and TKG250 also include protective holster, USB cable, and Extech XPorter software. Common Functions Description Thickness Range (in Steel) 5MHz probe: 0.040 to 20" (1.0 to 508mm); 10MHz probe: 0.020 to 20" (0.50 to 508mm) 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 (only on the TKG150/TKG250 models) Illuminating Keypad F1 = Red, F2 = Yellow, F3 = Green for easy, go/no-go testing 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 Battery Life Up to 50 hrs Up to 50 hrs (20hrs w/backlighting) (20hrs w/backlighting) 8 to 14hrs (depends on operating conditions) Specifications subject to change without notice.
