The AlphaGage+ series is a hand-held ultrasonic thickness gauges available for corrosion, precision or combined for both.
The Sonatest AlphaGage+ series is definitely a key asset for inspectors, maintenance operators or QA technicians looking to measure essentially any engineering material thickness as it combines years of ultrasonic design and knowhow.

Packaged in an extremely rugged and ergonomic hand held enclosure, the AlphaGage+ is a versatile piece of equipment as it can be used to perform integrity assessment of metal steel works affected by erosion or corrosion processes as well as measure precisely the thickness of critical pieces of equipment which have very strict quality control requirements. The AlphaGage comes in 2 versions, corrosion, and precision:

Corrosion package (Dual Element Probe)

As a primary inspection tool for corrosion assessments, the Sonatest AlphaGage+ instrument uses dual element transducers in a Pitch & Catch configuration to measure accurately the remaining wall thickness of metal structures subject to corrosion. Dual element transducers have a transmitting element and separate receiving element located side by side, the use of Pitch & Catch reduces any measurement problems which may result from material surface issues.

This product is a key tool to inspect ageing assets and solve problems in many industries but especially, Oil & Gas or Petrochemicals.

Typical applications include:

  • metal pipe works
  • pressure vessels
  • structural parts
  • storage tanks

Precision Package (Single Element)

The Sonatest AlphaGage+ instrument uses single element transducers in Pulse-Echo configuration in order to measure to higher accuracy than corrosion gauges. This is often required to meet very strict quality control requirements such as experienced in the Aerospace and Automotive industries.

With a wide offering of quality probes, delay line wedges and software options, the Sonatest precision gauge offering is very versatile.

Typical applications include:

  • Steel
  • Aluminium
  • Glass
  • Plastic
  • Rubber
