The Extech TKG250 Digital Ultrasonic Thickness Gauge is designed in compact, handheld, rugged housing ideal for field use. The ultrasonic technology allows for non-destructive thickness measurements for primarily steel structures. The TKG250 features a color LCD display with red, yellow and green visual alarm indications. The variable adjustment function is in 1dB steps from 20 to 90dB or Automatic Gain Control (ACG) for waveform. The TKG250 also has a file compare feature as a real time corrosion monitor, and is a 100k datalogger with export to Excel for trending and reporting.

The Echo to Echo function measures the metal thickness only. The differential mode displays the difference from the actual thickness measurement and a user entered reference value. The TKG250 also features velocity mode with displays acoustic sound speed.
