EchoPure is an ideal couplant for very cold inspection (liquid gas piping and refrigerant lines) and will not frost or attenuate at temperatures as low as -60°F. EchoPure is excellent for high temperature use such as warm welds up to 350°F and on pipe in the desert summer sun, where slow evaporation and long inspection windows are desired. With its low toxicity, EchoPure is a good choice for inspection in food processing plants.

EchoPure is a water-free, water-soluble ultrasonic couplant that has a broad operating range, is slow drying and provides excellent transducer lubrication. It is low toxicity and environmentally friendly.
