- 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 Min/Max depth, beeps and display flashes as well as keypad illumination;  vibrate

- 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 (ACG) for waveform

- B-Scan - Displays a cross section of the test piece: Encoded or Non-Encoded - displays with optional encoder

- 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

- Datalogger: Records 100K readings in linear, 2D, 3D grid or boiler alphanumeric files, 20 character file name, export to excel via Extech XPorter interface program, also compatible with Ultrapipe. TKG250 also has fi le compare and grid review features
