    Description

    Echo 4 HT™ is an ultrasonic couplant that comes in the form of a fluid. It is perfect for pumping and automated crawlers and thickness gauging of smooth or polished surfaces. It has a broad operating range of -70 °F to 450°F (-56°C to 230°C) and is also water soluble with low toxicity and is an excellent lubricant for helping you perform your ultrasonic inspections.

    Features

    • Broad operating range -70 °F to 450°F (-56°C to 230°C)
    • Water soluble: easier to remove than most fluid ultrasonic couplants by wet or dry wiping or water wash.
    • No “oil slick” when used where couplant may drip into a body of water.
    • Low toxicity
    • Compatible with a broad range of materials including most metals, plastics and composites
    • Good Surface wetting due to low surface tension and solvent properties.
    • Slow Drying at ambient temperatures
    • Contains no glycerin which can interfere with subsequent penetrant inspection.
    • Environment and operator friendly – no formaldehydes, nitrates, nitrites or glycol ethers.
    • Minimal residue
    • Removal: Wipe with wet or dry paper or cloth rag or water wash.
