Echo Ultrasonics has recently become the exclusive distributor of SpectrumGlide AUT-NDT Fluid Couplant in the U.S. and Canada.
SpectrumGlide, developed by Eclipse Scientific, has a viscosity formulated to reduce runoff and provide longer dwell time at temperatures from -50° F to 730° F (-45° C to 387° C).
The addition of SpectrumGlide gives Echo Ultrasonics a full range of automated ultrasonic testing fluids, with viscosities ranging from 125 to 5000 cps and covering temperatures from -70° F to 1200° F (-57° C to 649° C).
SpectrumGlide’s formulation results in faster and more efficient testing by allowing it to remain on pipes, tanks and other surfaces longer without draining off. Because it can be used in testing environments up to 780°F (415°C), it’s a versatile fluid for high-temperature AUT applications.
AUT uses automatic equipment to run a variety of inspections in numerous industries, from corrosion mapping to thickness gauging to weld inspection. For example, AUT is an efficient and accurate method for analyzing the integrity of pipeline welds in the oil and gas industry.

Echo’s automated ultrasonic testing fluids offer solutions for those who’ve encountered problems with other fluids. Often, fluids are too thick to pump, run off too fast, smoke too much, auto-ignite, freeze or vaporize so quickly that there’s no time to conduct the inspection.
With AUT fluids in multiple viscosities (thicknesses) spanning a broad range of temperatures, Echo has solutions to each of these problems. Several Echo AUT fluids are water-soluble, too, so they don’t leave a film on water when used at sea.
Echo AUT fluids have viscosities ranging from 125 to 5000 cps and covering temperatures from -70° F to 1250° F (-57° C to 675° C).
The five AUT fluids listed below are arranged by increasing Operating Range:
Echo 4HT is a water-soluble fluid with an operating range of -70° F to 450° F (-56° C to 230° C). It has low toxicity and good surface wetting. Echo 4HT is slow drying and is compatible with a broad range of materials, including most metals, plastics and composites.
VersaSonic fluid is a plant-based, biodegradable fluid with low toxicity and an operating range of -10° F to 700° F (-23° C to 371° C). Above 400° F (200° C), VersaSonic works best when sprayed or pumped (discharged) at the point of use.
Echo 8HT features minimal residue in a broad range of AUT and MUT ultrasonic flaw- and thickness-gaging applications, from -50° F to 800° F (-45° C to 425° C). The Echo 8HT line is compatible with all metals and most plastics. Echo 8 HT is available in three viscosities: grades 1, 4 and 10.
SpectrumGlide, a high-performance fluid for high-temperature testing, has a viscosity formulated to reduce runoff and provide longer dwell time at temperatures from -50° F to 730° F (-45° C to 387° C). SpectrumGlide was developed by Eclipse Scientific and is distributed under license by Echo.
EchoTherm Extreme fluid is the highest-temperature fluid couplant available. EchoTherm Extreme is a high-viscosity fluid that produces less smoke and minimal residue. It has the broadest operating range, from -40° F to 1250° F, and its auto-ignition point is above 1300° F (704° C).
No matter the testing environment or application, it’s likely that Echo Ultrasonics has — or can develop — just the right couplant. Give the Echo experts a call to find the right couplant for your needs or to request a sample.
Thanks to everyone who visited with us at ASNT in Nashville.
Couplant sample requests are being entered and we will be in touch soon. We had many discussions regarding the use and success of EchoPure for Phased Array inspections. EchoPure is the solution for phased array element drop out and the resulting difficulty in reproducing flaw indication. The water-free formulation and strong coupling film of EchoPure provides a continuous film between the part and the transducer and resists “air gap puddling” which is common with couplants containing water.
Vaporization of VersaSonic™ vs Sono 600®
The above plot is a technical representation of why VersaSonic (top line) outperforms Sono 600 (bottom line). The plot depicts the weight loss of each couplant due to vaporization over time at 200°C (392°F). Sono 600 loses significantly more mass and vaporizes faster than VersaSonic. Vaporization produces gas bubbles which both attenuate and scatter ultrasound as well as degrades the rheology of the product (coupling doesn’t last as long, dries faster and gets sticky or tacky sooner).
While many Echo customers that have switched to VersaSonic from Sono 600 have observed these characteristic in practice, this test demonstrates the technology behind the experience.
VersaSonic is the ideal high temperature ultrasonic couplant when working under 750°F (400°C). The response is instant as there are no plastic polymers in VersaSonic that need to melt before transmission occurs. At higher temperatures (above 350°F / 177°C) its useful service life is longer than competitive couplants. The auto-ignition temperature for VersaSonic is 788°F (420°C). VersaSonic is available in two viscosities:
- High Viscosity – ideal for spot inspections
- Medium Viscosity – best for spreading

We’ve expanded our line of Echo 8HT fluid UT couplant to include three additional viscosities. Performance of a broad range of AUT and MUT ultrasonic flaw and thickness gaging applications from -50°F to 800°F (-45°C to 425°C) is possible with these four grades, with minimal residue and great signal to noise ratio.
Grade 1 is the lowest viscosity fluid (100 cST) for long or small diameter lines and quick spreading.
Grade 4 is Echo’s standard viscosity fluid (400 cST) and is usually a good compromise between pump ability and run-off at the transducer.
Grade 6 is a higher viscosity fluid (850 cST) that minimizes run-off at the transducer, however, requires system “pump ability” testing.
Grade 10 is a very thick fluid (5,000 cST – honey like) for MUT. It spreads easily over large hot surfaces, stays in place and leaves minimal if any residue.
Introduced in the mid 1970’s by Aerotech / Krautkramer Branson and sold by GE Inspection Technologies for decades, HiTempco has been the standard of performance in silicone based ultrasonic couplants. With a broad temperature range of -50°F to 775°F (-45°C to 412°C), its applications range from high temperature thickness gauging and flaw detection to ambient and low temperature coupling where no corrosion, broad material compatibility, long service life and low toxicity are considerations.
- Very high viscosity
- No residue
- Strong corrosion inhibition
- Non-toxic, non-irritating
- Low environmental impact.
- Contains no perfluorocarbons, peanut or tree nut oils.
-50°F to 775°F (-45°C to 412°C)

You may be aware that VersaSonic® has superior performance from -10 to 750°F, however, did you know:
- VersaSonic is available in medium viscosity for optimal spread-ability and high viscosity to “stay in place” on a transducer, pipe or overhead surface.
- VersaSonic is available in open-top 1 and 5-gallon pails (5-gallon dispensing pump included at no charge), 1 gallon and quart cubitainers.
- VersaSonic is a versatile broad temperature couplant. The world’s largest producer of power generating equipment has standardized on VersaSonic for use at ambient temperatures due to its compatibility with their electronic components.
- Refineries and heat treatment plants use VersaSonic because its useful service life is up to three times longer than competitive couplants at temperatures above 350°F.
