  • Measurement of transit time and pulse velocity at superficial and through sonic testing
  • Testing of strength, uniformity and type of concrete, brick and other materials
  • Detection of voids, cracks and other anomalies, measurement of perpendicular surface crack depth during technological control and inspection of objects
  • Estimation of concrete maturity degree at solid-cast concreting
  • Determining of density and elasticity modulus of materials, sonic index of abrasives
  • Estimation of honeycombing, cracking and anisotropy of materials
  • The results are not critical to the pressing force of transducers (patent)
  • Due to the increased energizing pulse and enhanced correlation "signal – noise", the instrument is efficient at large bases of sonic testing
  • Universal transducers with automated combination of the transmitter voltage and the receiver gain, ensures an optimum received signal level, guaranteeing accurate and stable measurements
  • Pulse echo (single side access) transducer with fixed base:
    – handle made from superlight and warm material enables to test objects with poor strength at minimum pulse velocity from 1200 m/sec
    – 120 mm base which is necessary to graduate the instrument using sample cubes of 100 mm side
    – exponential durable transducers with dry point contact for rough surfaces
  • Transducer type depends on the version
  • Pulse echo and through transmission waterproof transducers with FISHER connectors (option) to examine the hydrotechnical objects under water
  • High-resolution 3.5-inch color TFT display
  • Built-in lithium accumulator of a large capacity and power unit for continuous operation and restoration
  • Automatic stabilization of the first arrival of the ultrasonic pulse mark position
  • Measuring time and speed of ultrasonic pulse during pulse echo and through transmission testing
  • Result acquisition after an automatic series of 2 ... 10 measurements
  • Testing strength of concrete and brick and strength quality of concrete
  • Measurement of perpendicular surface crack depth using «Russian» and «English» methods
  • Calculation of density, modulus of elasticity and sonic index of materials
  • Universal and individual concrete correlations with user-specified materials
  • Up to 1000 testing protocols including data and type of object
  • Russian/English menu availble
