EMA Thickness Gauge NOVOTEST UT-3A-EMA

NOVOTEST UT-3A-EMA is designed to measure thickness of objects, such as pipes, tanks, sheet products, ship bottoms  and other parts, made of metals and alloys, without application of couplant and advance surface preparation, through air gap or a layer of rust, dirt, salt or other non-conductive coatings (paint, varnish, enamel, plastic, etc.) up to 6 mm. Also it is used for evaluation of anisotropy degree of the material. Pulsed electro – magnetic technology implemented in the EMA transducers allows user to put the probe not exact perpendiculary to the surface, but up to 25 degrees of skew and get correct readings.

  • Thickness measurement (steel) – 2…60 mm
  • Convenience and easy in operation
  • Probe type selection
  • Preset velocity of ultrasound (1000 – 9999m/s) with 1 m/s step
  • Without application of couplant and advance surface preparation, through air gap or a layer of rust, dirt, salt or other non-conductive coatings (paint,varnish, enamel, plastic, etc.) up to 6 mm
  • Allows user to put the probe not exact perpendiculary to the surface, but up to 25 degrees
  • Acoustic contact indication on the graphic display
  • Fixation of the last measurement result in the removal of the transducer surface
  • Power supplied by standard AA batteries
  • Shock-resistant housing with a protective silicone bumper-case
  • The device has a bright contrast LCD display
  • A-scan, B-scan, calibration settings
  • Three thickness measurement modes:
  • Automatic
  • Manual mode, measurements are made using maximum in the first gate
  • Manual mode, measurements are made using two maximums in two gates
