Surfer- Ultrasonic Pulse Velocity Tester

The Surfer (UK1401)- Ultrasonic Pulse Velocity Tester

INTRODUCTION

The Surfer Ultrasonic Tester is suitable for the measuring of time and velocity of ultrasonic p-waves in hard materials including concrete, rocks and ceramics. The Surfer has major advantages of other products on the market in that it doesn’t require coupling gel and takes seconds to perform the test. This improves work flow, especially where a large volume of testing is to be carried out.

APPLICATIONS

There are many applications for the Surfer, including:

The determination of the strength and integrity of concrete. The evaluation is based on correlation the velocity of ultrasound waves in material and its mechanical parameters and physical condition
Search of 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 crack depths perpendicular to the concrete surface
Evaluation of porosity and fissuring in materials

FEATURES

The device features an ergonomic body made from light weight shock-proof plastic that makes it very convenient to work with in field. With two built-in DPC (dry point contact) transducers it allows testing to take place without contact liquid. The transducers are wear-resistant and are not influenced by condition of surface allowing the user to without surface preparation.

Easy testing in seconds
Automated crack depth mode
Built-in automatic gain regulation system
Audible indication of test success
Data logs up to 4000 readings with the ability to group readings, allows you to organise data
