PZX1-DL series ultrasonic thickness gauges

Dakota NDT PZX1-DL precision thickness gauge

The Dakota NDT PZX1-DL is a single element precision thickness gauge with a digital display and four measurement modes (Pulse-Echo, Echo-Echo, Interface-Echo and Plastics), data logger, USB-C connectivity and automatic TDG.

Precision thickness gauge: single element, digital display
4 measurement modes: Pulse-Echo, Echo-Echo, Interface-Echo, Plastics
5–20 MHz transducers: delay line and contact
High resolution: down to 0.001 mm
Automatic TDG: with manual override, in all modes
Data logger: 40 files × 250 readings (10,000)
USB-C + Bluetooth: .csv data download; optional BT module

The PZX1-DL is a single element precision instrument which, thanks to its four measurement modes, covers a wide range of applications: from thickness on metals to measurement through a delay line, right through to plastic materials. The 120 MHz FPGA timing and the 100 V spike pulser ensure high resolution.

Automatic time dependent gain (TDG), with manual override, is active in all modes. It features a data logger (10,000 readings), USB-C connectivity with .csv data download and optional RS232 or Bluetooth modules for connection to data collectors and custom apps.
