The couplant is a fragrant gel based on water, and better than oil, grease, or water: It achieves excellent coupling, does not soil, and is free from sulphur, halogen and phosphor; it contains a corrosion inhibitor, is non-irritant and non-flammable. Temperature range: 0 °C through +80 °C
Order numbers:
This high-temperature resistive grease is based on silicon oil and allows measurements on components with surface temperatures between -40 °C and +290 °C.

ECHOFLUID is an odourless liquid with a viscosity similar to water or oil, but grants better coupling than other liquids. ECHOFLUID is recommended for higher frequencies and wall thickness measurement. It is completely removable, an excellent corrosion inhibitor and non-irritating to skin.

Indispensable for manual or automated ultrasonic testing in immersion or squirter techniques:
Water is an ideal couplant, but generates corrosion on components and testing mechanics. Common corrosion inhibitor very often remarkably reduce the tool life of ultrasonic probes. ECHOKOR is added to the water in 1 to 2.5 % per volume and thus reliably protects even materials sensitive to corrosion. ECHOKOR can easily be dissolved in water and bothers neither skin nor probes..

Water Additive is an extra low foam corrosion inhibitor and is convenient for the use in couplant circuits.

Useful auxiliary device for the daily check-up of the test range adjustment of your ultrasonic instrument or to check linearity and sensitivity:
The adjusting standard is equipped with a Lemo 1 – plug and is connected like a one-crystal probe to the transmitter socket of any arbitrary ultrasonic flaw detector. An echo sequence of 10 consecutive back wall echoes (50 mm steel with cL = 5920 m/s) is typically used for instrument calibration. Also available with 100 mm steel.
