Signal™ UT Couplant: Works Better, Lasts Longer, Costs Less
In ultrasonic testing, time and material costs add up quickly—especially when couplant needs constant reapplication. Frequent stops to reapply product don’t just slow inspections down—they also increase overall usage and cost.
The solution is here with our Signal UT Couplant.
Anywhere you’re using Ultragel®, Signal works better, lasts longer, and costs less—delivering measurable improvements in both performance and efficiency.
Put simply:
There has never been a gel couplant that performs like Signal.
By combining long-lasting performance, resistance to thinning, and reliable signal quality, Signal helps inspectors:
* Reduce reapplication
* Use less product
* Lower overall costs
* Improve inspection efficiency
A Couplant That Lasts Longer
Unlike competitors’ gel couplants, Signal is formulated with two specialized polymers that prevent it from thinning when exposed to oxides or metal salts.
In real-world applications, this makes a significant difference.
When you return to a previously inspected area, Signal remains effective—eliminating the need for reapplication. This extended performance allows inspectors to move faster and more efficiently without constantly stopping to reapply couplant.
Because Signal lasts longer and doesn’t thin, you use less overall—reducing your total couplant cost per inspection.
Reliable Performance in Demanding Conditions
Signal doesn’t just last longer—it performs where it matters most.
Get clear, reliable readings with Signal Couplant, especially in applications above 5 MHz. Its formulation supports strong signal transmission, even on rough, corroded surfaces where signal to noise ratio can be a real issue.
Using Signal Couplant means improved signal clarity and greater confidence in your inspection data. Signal—the name says in all.
Formulated for Efficiency and Your Equipment
Beyond performance and longevity, Signal also improves the inspection experience itself.
Its more lubricious formulation allows the transducer to glide smoothly across surfaces, reducing drag during scanning. This not only makes inspections easier, but also helps minimize wear on transducers over time.
Upgrade Your Inspections with Signal
If you’re looking to reduce downtime, lower material costs, and improve performance in demanding ultrasonic testing applications, Signal delivers on all fronts.
