Operating in through transmission mode using two transducers, the soft tipped transducers are for use with Sonatest Dryscan capabilities available on flaw detectors such as the Masterscan or Prisma series. Applications include the testing of composites, rubber, wood, ceramics and friction material. No surface preparation is required for the majority of applications and it is an ideal solution for test specimens with complex shapes. The roller probes (RP) are mainly used where automated testing is required.
