Echo 8 HT™ Fluid for AUT and Robotics
Overview
Price range: $675.00 through $5,100.00
Echo 8 HT™ is a line of high temperature, slow drying ultrasonic fluids with an excellent safety profile.
Echo 8HT performs in a broad range of AUT and MUT ultrasonic flaw and thickness gauging applications from -50°F to 800°F (-45°C to 425°C)
Echo 8 HT High temperature ultrasonic coupling fluids are available in three viscosities; Grades 1, 4 and 10.
Echo 8HT Grade 1 is the lowest viscosity fluid for long or small diameter lines and quick spreading
Echo 8HT Grade 4 is Echo’s standard viscosity fluid and is usually a good compromise between pump ability and run-off at the transducer.
Echo 8HT Grade 10 is a very thick fluid 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.
Echo 8HT three grades offer viscosity options.
Grade 1: Low viscosity (100 cST) for long and/or small diameter lines
Grade 4: Standard viscosity (400 cST) for shorter and/or wider lines
Grade 10: Very thick fluid (5,000 cST – honey like) for MUT

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.
