    Steel Thickness Range5MHz probe: 0.040 to 20″ (1.0 to 508mm); 10MHz probe: 0.030″ to 2″ (0.76mm to 50.8mm)
    Material velocity calibration range0.200 to 0.7362 in/μS (0.508 to 18.699mm/μS)
    LanguagesEnglish, French, Spanish, Italian, Czech, German, Portuguese, Slovak, Finnish, and Hungarian
    Hold ModeHolds display to retain last thickness reading with reverse video display
    Freeze ModeFreezes display (ideal for high temperature readings)
    Fast Min/Max ModeDisplays Min or Max and actual thickness value at 20 measurements/sec
    AlarmsAudible beeping; illuminae flashing display and keypad; and vibration feedback
    Illuminating KeypadF1 = Red, F2 = Yellow, F3 = Green for easy, go/no-go testing
    Gain – Variable adjustmentIn 1dB steps from 20-90dB or Automatic Gain Control (AGC) for waveform
    B-Scan – Displays a cross section of the test pieceDisplays 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 EchoMeasure the metal thickness only (paint & coatings do not affect base material thickness value)
    Differential ModeDisplays the difference from the actual thickness measurement and a user entered reference value
    Velocity ModeDisplays acoustic sound speed to measure thickness of unknown materials
    DataloggerStores 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
