Manual Non-Destructive Quality Test System – NDT-MAN

Resonant Inspection for Onsite Evaluation and Spot Checks

Resonant Acoustic Method is designed to help deliver fully inspected parts, economically and on time.  Every component has a unique resonant signature or pattern that reflects its composition.  NDT-RAM™ detects deviations from the expected signature or pattern.  The NDT Manual System has all the core components necessary for Resonant Inspection, including the smart digital controller, impact hammer, microphone, software and rugged travel case.  The system provides a completely portable solution for quality testing of a wide range of components and is ideal for spot testing, part investigation and troubleshooting.


  • Simple - pass/fail result is returned by the NDT-RAM system
  • Compact - fits easily inside a laptop case
  • Portable - ideal for spot checking in the field
  • Versatile - ideal for new part set-up, investigation, troubleshooting

All of the NDT-RAM systems are ideal for 100% inspection requirements of manufacturers or users of powder metal, metal injection molded (MIM), castings (including ductile iron), forgings, stampings or welding. NDT-RAM provides screening for cracks, chips, holes, out-of-tolerance dimensions, variations in hardness, residual stress, bonding failures and heat-treating processes. Manufacturers that have significant inspection costs (either material or labor costs), produce or use safety-critical parts, have substantial scrap costs due to false rejects or simply want to improve their part quality can benefit from NDT-RAM technology.
