Thickness Gauge TKG150

TKG150: Digital Ultrasonic Thickness Gauge/Datalogger

Compact rugged meter for non-destructive thickness measurements

The Extech TKG150 Ultrasonic Thickness Gauge, from Agile Microsys, is a durable tool for non-destructive thickness measurement, especially on metals like steel. It offers a wide measurement range, a sunlight-readable backlit display, and memory for up to 100,000 readings. Features like Echo-to-Echo for accuracy, B-Scan imaging, and vibration alarms enhance its usability in industrial quality control and maintenance. The TKG150 includes essential accessories, such as a 5MHz transducer and software for data management.

Fast Min/Max Mode
Displays Min or Max and actual thickness value at 20 measurements/sec
Units
Inches/Millimeters/Microseconds
Alarms
Audible beeping; illuminate flashing display and keypad; and vibration feedback
Illuminating Keypad
F1 = Red, F2 = Yellow, F3 = Green for easy, go/no-go testing
Gain – Variable adjustment
Low, Standard, High
B-Scan – Displays a cross-section of the test piece
Displays a visual cross-section of the 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 the 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.
