Thru-Paint Mode (E-E) eliminates the Coating and only measures Wall Thickness

Sturdy and accurate ultrasonic thickness gauge based on the ultrasonic pulse run-time method.

6 ultrasonic probes with frequencies ranging between 2 and 10 MHz in different designs offer a broad spectrum of applications and thickness measurements ranging from 0.65 mm to 500 mm. A high temperature ultrasonic probe is also available, designed for measurement of hot materials with temperatures of up to 350 °C.

The device is equipped for automatic detection of the intelligent ultrasonic probes and re-calibration is not required upon switching probes. The calibration data of the sensor is saved in the probe.

Uninterrupted scanning of a part for thinning is possible at the minimum mode.

Features

  • Includes Factory "Works" Calibration Certificate, NIST Cert Optional $100

  • Suitable for measurement of various materials including steel, stainless steel, aluminum, glass, plastics (PS/PE)
  • Adjustable units inch/mm
  • Resolution of 0.001" (0.01 mm)
  • Automatic identification of probes
  • Automatic Probe Zero function
  • Uses Pulse-Echo (P-E) or Echo-Echo (E-E, thru-Paint) Principles of Ultrasonics
  • Sensitivity can be set to "Auto" or "Manual"
  • Several Transducers are optionally available including one for High Temperature materials (350 °C)
