Echo 8 HT™ High temperature ultrasonic coupling fluids are available in three viscosities; Grades 1, 4 and 10.  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 three grades. 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 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. All grades of Echo 8 HT provide excellent corrosion inhibition on ferrous metals, leave minimal residue and are compatible with all metals and most plastics.

Reviews

  1. Chad H. Senior NDE, API Inspector

    We have been using it for shear wave inspections on high temperature components and have been quite happy with how it has been working. The big things I needed from it originally was to be spreadable, be able to stay on the surface and not leave a residue, all of which this couplant has provided.
