The Dakota PZX Precision Thickness Gauges (PZX-7) are ultrasonic precision thickness gauges with ThruPaint technology, available as the PZX1 (part number Z-307-0002) and the data-logging PZX1-DL (part number Z-308-0002). The Dakota PZX Precision Thickness Gauges measure the thickness of thin substrates accurately and can calibrate to a variety of materials using a one point calibration option.

On thin material, a small error is a large share of the wall thickness, so resolution and repeatability decide whether a part is in tolerance. ThruPaint technology lets the Dakota PZX Precision Thickness Gauge read the substrate thickness without removing a coating first, which saves stripping paint to take a measurement. Resolution is 0.01mm and the velocity calibration range runs from 309.88 to 18,542m/s, covering metals and composites. Measurement ranges of the Dakota PZX Precision Thickness Gauges include pulse-echo from 0.63 to 914.4mm, echo-echo on a single delay line from 0.152 to 25.4mm, and plastics from 0.127 to 6.35mm, with single element transducers from 5 to 20MHz.

Both models of the Dakota PZX Precision Thickness Gauges share High Speed Scan Mode, Differential Mode, a limit alarm, auto V-path correction and a repeatability and stability indicator, with 12.7mm high digits and a switchable LED backlight. The PZX1 has no data logging, while the PZX1-DL stores sequential data, 40 files of 250 readings each, for 10,000 readings. Factory calibration for the Dakota PZX Precision Thickness Gauges is traceable to NIST and to MIL-STD-45662A, the military standard for calibration system requirements.
