High Resolution gauge for measuring thin materials with 0.0001" resolution

Range: 0.0060 - 1.000 inches - 0.15 - 25.4 mm

Resolution: 0.001" (0.01 mm)

Datalogging: NO

Measuring Range in Steel
0.0060 - 1.000 inches
0.150 - 25.40 mm

The TI-007 Precision Ultrasonic Thickness Gauge is a precision ultrasonic wall thickness gauge specifically suited to make extremely precise and high-resolution measurements on thin-walled metal and plastics.  The TI-007 Precision Ultrasonic Wall Thickness Gauge is packaged in a sturdy extruded aluminum housing which is sealed for excellent environmental protection assuring trouble-free use even in the toughest field and production environments.

The gauges have a MEASURING RANGE from 0.0060 to 1.0000 inch, (0.15 to 25.40 mm). Using a single element delay tip transducer, the gauges will measure thin materials and automatically remove any coatings in ECHO-TO-ECHO MODE as well as automatically switch to interface echo mode when measuring thicker materials and plastics.
