Couplant is used to exclude the air between the surface of the ultrasonic probe to the test component. Couplant is packaged in many sizes and is available as a liquid or in a powder. Contact PCTE's team to special order to your exacting requirements.

Collect high-density, georeferenced GPR data across wide areas and view the subsurface in 3D as you scan. Choose the GX2 array for SUE and utility mapping, or the GX1 array for structural, bridge and pavement investigations.
Best suited to:
Best suited to:
Recommended array: GX2
Recommended array: GX1
Cover more ground
Collect multiple parallel profiles in one pass instead of uilding a grid line by line.
See results during acquisition
View georeferenced radargrams and time-slice information in the field rather than waiting until the data is returned to the office.
Produce repeatable mapped data
Combine wheel-positioned GPR data with GNSS, project coordinates and survey linework.
Use one platform for two very different applications
Exchange GX1 and GX2 arrays without purchasing two complete cart platforms.
The GX2 transforms the GS9000 into a high-density subsurface utility mapping system. Its 11-channel, low-frequency GPR array captures an 83 cm-wide swath in each pass, helping operators detect and map buried pipes, ducts, cables, voids and other subsurface features. Live georeferenced data lets SUE teams review coverage on site and produce accurate CAD, GIS and project-coordinate deliverables.
1. Plan the survey
Load satellite imagery, CAD information, project coordinates or survey control.
2. Collect dense multichannel data
Survey an approximately 0.82 m-wide swath with 11 channels in each pass.
3. Review data live
Examine radargrams, georeferenced time slices and marked features while still on site.
4. Interpret and digitise
Add points, linework, tags, photographs and field observations.
5. Process and deliver
Merge survey areas, apply processing and export mapped information for the customer’s CAD, GIS or reporting workflow.
SuperSoniX is an enhanced performance couplant with a broad operating range, slow evaporation rate and gel viscosity that remains in place.
Contains glycerin. Not for aluminum aircraft inspections.
UltraSoniX is a high-performance couplant, available in medium viscosity, ideal for spreading.
Removal: Wipe with wet or dry paper or cloth rag or water wash.
Single packet powdered UT couplants provide an economical solution for travel, remote access inspections and storage limitations.
EchoMix Single is a one-part (one packet) powder, easily mixed in ambient water in five minutes, providing a strong, continuous coupling film that adheres well to vertical and overhead surfaces. Single mix packet, one step mixing.
Removal: Remove with a dry rag, water and brush or pressure washer.
Air Bubbles: All powder couplants will form small air bubbles after mixing if water is not de-aired. These small bubbles usually do not negatively affect the use of the couplant and will dissipate in 3-4 days. If an air bubble-free couplant is desired immediately, use hot water and allow to stand overnight; then proceed with adding the powder couplant.
The Blue Color is a visual marker to ensure uniform distribution of the corrosion inhibitor by encouraging thorough mixing.
VersaSonic® is Echo Ultrasonics' most versatile couplant, from high temperature on turbine rotors to extreme weather inspections. VersaSonic is a low-toxicity, biodegradable couplant that does NOT contain peanut oil.
Removal: wipe with paper or cloth rag. If complete removal is required, dish detergent and water or a chemical degreaser can be used.

The GX1 transforms the GS9000 into a high-resolution structural assessment system for concrete slabs, bridge decks and pavements. Its dense, dual-polarisation array captures detailed 3D data across wide areas, supporting reinforcement and cover mapping, moisture and deterioration assessment, and analysis of asphalt and pavement layers. Live visualisation helps confirm survey coverage on site, while post-processing tools produce clear, report-ready condition maps.
1. Define the inspection area
Import the structure, bridge, pavement or survey background.
2. Collect closely spaced profiles
Capture 35 longitudinal and 15 cross-polarised channels with dense spacing.
3. Review coverage in the field
Use live radargrams and time slices to confirm that the required area has been captured.
4. Process the dataset
Apply velocity, gain, background removal, migration, filtering and topographic correction as appropriate.
5. Generate diagnostic maps
Create depth slices, reinforcement maps, layer information or application-specific condition maps.
6. Integrate with the engineering assessment
Export figures, mapped anomalies and raw data for inclusion in the engineer’s final interpretation and report.
