Echo Ultrasonics HiTempco+

Echo Ultrasonics HiTempco+

HiTempco+ is a high-temperature ultrasonic couplant designed for demanding non-destructive testing (NDT) and ultrasonic inspection applications. It delivers instantaneous ultrasonic response, ensuring fast, accurate signal transmission in elevated-temperature environments.

Engineered for reliability, HiTempco+ leaves no residue or varnish after use and provides long-term corrosion inhibition for steel and cast iron, helping protect inspected surfaces during and after testing.

Compatible with most metals and plastics, HiTempco+ supports a wide range of ultrasonic inspection applications across industrial, manufacturing, and field environments. Its formulation is designed with low environmental impact, containing no perfluorocarbons, peanut oils, or tree nut oils.

HiTempco+ is an ideal ultrasonic couplant for technicians requiring consistent performance, material compatibility, and surface protection in high-temperature inspection conditions.

Available across Canada through Stuart Hunt & Associates.
