Wall Thickness Gauge – MiniTest 400 Range

Minitest 400The MiniTest 400 is a sturdy and accurate non destructive ultrasonic wall thickness measurement gauge ideal for measuring hard materials such as metal, synthetic material, glass, ceramic etc., and covers a range of shapes and hollow bodies of all kinds like tanks, pipes and more.

Based on the ultrasonic pulse run-time method, we offer three variations of this wall thickness gauge depending on the users requirements and budget.  Users can choose from 6 ultrasonic probes with frequencies ranging between 2 and 10 MHz in different designs offering 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 instrument is equipped for automatic detection of the intelligent ultrasonic probes and re-calibration is not required upon switching probes. 

Applications:

Non-destructive wall thickness measurement of:

  • Hard materials like metal, synthetic material, glass, ceramic etc.
  • Hollow bodies of all kinds like tanks, pipes etc.

Various measurement modes available:

Standard: The standard mode displays the active measurement reading.

Minimum: The lowest measured value (= thinnest point) is displayed while measuring. This mode is suited for measurement on curved surfaces or to locate the thinnest wall thickness.

Differential: Shows the differential value between the required thickness and the effective thickness measured.

Alarm (Limit): Activates an optical and acoustic alarm when values exceed or fall short of the threshold values.

Scan: Particularly suitable for quick measurements at high material temperatures.

Features:

  • Non-destructive wall thickness measurement ranging between 0.65 mm and 500 mm
  • High measurement precision and repeatability
  • High resolution of 0.01 mm
  • Scan mode with 10 measurements per second
  • Low voltage memory
  • Minimum mode to detect thinning due to erosion or selective/pitting corrosion
  • Alarm mode with optical and acoustic signals to indicate exceeded limit values
  • Differential mode to indicate deviation from set value
  • Saving and evaluation of measured values by built-in data logger
