The PX-7DL is a precision ultrasonic wall thickness gauge specifically suited to make extremely precise and high-resolution measurements on thin-walled 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 PX-7DL incorporates a built-in memory for 1000 data points that can be separated into 10 separate "batches." The stored data can be downloaded to a serial printer or a personal computer. A Windows compatible data transfer program is supplied at no additional cost.

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.
