Selecting the Right Couplant
Selecting the right couplant for your UT inspection is critical to get the best measurement data and prevent unnecessary risks.

Surface Preparation
The Ionix HS582i dual element transducer is suitable for testing on
several different materials, surfaces and applications, however the
surface condition of the test piece or asset being measured, needs
to be able to transmit sound energy through the contact surface. As
with conventional transducers, preparing the contact surface and
using appropriate couplant will increase the signal amplitude and
accuracy of your measurements.
Aligning your Probe
When measuring at high temperatures, the increased attenuation of the test piece, accelerated degradation of couplant and rough surfaces can mean that every decibel of signal is important to get the most accurate measurement. But with any transducer at any temperature measurements on small diameter pipes haveadditional considerations, with the curvature reducing the contact area of your transducer, and making it harder to align your probe perpendicular to the test piece surface, which can be detrimental to getting the best measurement.
Probe Resurfacing
The Ionix HS582i dual element transducer is suitable for testing on several different materials, surfaces and applications. The front face has an 2X increased wear resistance compared to standard probes to maximise lifetime. During extended use the front face may wear. The face of the transducer is vital to the accuracy of measurement and when worn will reduce its coupling efficiency. Up to 1.5 mm of wear can be re-surfaced to renew the device and extend its life.
