The Surfer (UK1401) - Ultrasonic Pulse Velocity

Surfer-UK1401-UPV

Specifications - Video - Measuring Mode

The UK1401 Surfer is an ultrasonic pulse velocity tester, it uses dry point contact transducers to determine an indirect UPV measurement, also known as a surface UPV.

The surfer is suitable for measuring the velocity of ultrasonic compression waves [also known as P-waves] in hard materials including concrete, rocks, and ceramics.

It is commonly used to compare the relative quality or strength of concrete and rock, and also to estimate crack depths in concrete structures. 

The Surfer's major advantage as a compact, handheld unit is immediate testing and feedback, the drypoint contact transducers require no gel or grease to measure with.

Applications

There are many applications for the Surfer, these are the jobs for which the surfer can be used, for detail on the measurement modes please look at two sections below. 

  • The determination of the strength and integrity of the concrete.
    • The Surfer includes an estimation of MPa compression strength with inbuilt calibration curves
  • Detect close-to-surface flaws by velocity decreasing or increasing around a potential flaw
  • Evaluation of the degree of anisotropy in composite materials
  • Evaluation of the degree of concrete aging
  • Automatically evaluation of concrete crack depths perpendicular to the concrete surface
  • Evaluation of porosity and fissuring in materials

It is the most common method to use ultrasonic pulse velocity to determine the quality of rocks. Surfer has been a very common tool for Rock testing in the Tunneling and Moning Industry. The ultrasonic Compression waves[P-Waves] are used to determine the strength of hard materials Like Rocks. 

Features

The device features an ergonomic body made from lightweight shock-proof plastic that makes it very convenient to work with the infield.

  • Built-in automatic gain regulation system
  • Audible indication of test success
  • Data logs up to 4000 readings with the ability to group readings
  • USB data transfer to PC
    • Data is exported as a .csv file
