A compact, ergonomic and handheld ultrasonic pulse velocity tester for concrete inspection. Featuring Light-weight plastic and built-in transducers with with a fixed 150 mm spacing.
Manual for ACS' Surfer UK1401.
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.
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.
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.
The device features an ergonomic body made from lightweight shock-proof plastic that makes it very convenient to work with the infield.
