**Specifications:**

-   Steel Thickness Range: MHz 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

-   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)
