Dakota Ultrasonics ZX-1 Ultrasonic Thickness Gauge

Dakota Ultrasonics’ ZX-1 Ultrasonic Thickness for detecting corrosion and pitting in many applications.


Dakota Ultrasonics’ ZX-1 Ultrasonic Thickness Gauge is a basic single-velocity gauge, ideal where the material thickness of a single material will be measured repeatedly.

Dakota ZX-1 is suitable for measuring the thickness of materials to evaluate for corrosion and pitting in tubes, pipelines, tanks, boilers, and other applications. Simply adjust the velocity using the ZX-1 keypad to consistently and accurately measure thickness of one material, locate blind surface pitting, or internal defects and flaws in a variety of materials.


  • Adjustable material velocity using keypad
  • Manual zero function
  • Pulse-echo measurement
  • Dual-element transducers (1 – 10 MHz options) with 4-foot cables
  • Locking quick-disconnect LEMO connectors
  • Custom transducers are available for special applications
  • Can measure reliably on curved surfaces with larger diameters.
  • Bar graph indicates stability of reading
  • Multi-function 7-segment 4.5 digit LCD display.
  • Low-temperature, custom LCD display (- 22˚F / – 30˚ C)
  • Extruded aluminium body with nickel-plated aluminum, gasket-sealed end caps
  • Sealed membrane keypad is resistant to water and petroleum products
  • IP65 protection rating
  • Operating temperature of -22 to 167˚F / -30 to 75˚C
  • Backlight on/off/auto selectable
  • Adjustable brightness (lo/med/high)
  • Two 1.5V alkaline, 1.2V NiCad, or 1.5V Lithium AA cells
  • Typically operates for 45 hours on alkaline and 23 hours on NiCad batteries
  • Low-battery indicator on display; automatic turn-off when battery is too low for reliable operation
  • Factory calibration traceable to NIST & MIL-STD-45662A
