Precision Ultrasonic Wall Thickness Gauge

Checkline Precision Thickness Gauge TI-007X

The TI-007X is a precision ultrasonic wall thickness gauge designed for high-resolution measurements on thin-wall metal and plastics.

Available with data logging or without.

The TI-007X is a precision ultrasonic wall thickness gauge designed for high-resolution measurements on thin-wall metal and plastics. It 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 TI-007X has measuring range in steel 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-Echo Mode (E-E) as well as automatically switch to Interface Echo Mode (I-E)when measuring thicker materials, For measurement of plastics, the user would select Plastic Mode (PLAS) and use the option Graphite Delay Line Tip (p/n X-633-0000).

Additional Measuring Modes include Differential (DIFF) where a user sets a "nominal value" and the gauge displays the ± difference between then nominal and actual wall thickness, Alarm (user-set Hi/Low Limits) trigger Hi/Lo LED's when the measured values are out of tolerance and Velocity Mode

The TI-007X can also be used with single element contact transducers for wall thickness measurements up to 36 inches (923 mm). Although the TI-007X does not have any built-in memory, it can transfer single values (value on the display) via the USB port to a PC or compatible data collector. No Software is required.
