● Features
     · Automated resonant frequency testing.
     · Fast testing-Automatically sweeps through range frequency.
     · Measures fundamental resonant frequencies-longitudinal, torsional and flexural.
     · Measures damping constnt 'Q'.
     · Manual mode for detailed examination and testing.
     · Memory for result storge.
     · Serial output to PC or Printer.    

● Benefits
     · Can be used to determine dynamic modulus of elasticty, rigidity, poisson's ratio.
     · Can be used to determine ultrasonic pulse velocity.
     · Can be used on a wide range of materials, including concrete, ceramics, refractory
       materials, glass, graphite, stone, etc.
     · Widely used for concrete freeze-thaw testing.
     · Also used for theminal cycling or thermal shock testing.
