CF-4H High Temperature Coupling Fluid

Made in the USACF-4H is a High Temperature coupling fluid is a biodegradable coupling fluid that provides an extended temperature range for ultrasonic thickness measurement.

CF-4H High Temperature Coupling Fluid facilitates the transmission of ultrasonic waves from a transducer/probe into the test material. Coupling fluid is required because the acoustic impedance mismatch between air and solids. Without couplant nearly all of the energy is reflected and little is transmitted into the test material. The couplant displaces the air and allowing sound energy into the test specimen so that a usable ultrasonic signal can be obtained.

Standard coupling fluid is water based and will evaporate around 97 ºC, however CF-4H High Temperature Coupling can be used at higher temeperatures up to 316 ºC

Temperature Range: -18 to 316 ºC

  • Temperature Range: -18° to 316° C
  • Very slow drying; allows for long-term coupling without reapplication
  • Excellent corrosion inhibition
  • Supplied in 118ml tube
