Imason Special probes are dedicated to particular applications that require different solutions than those of conventional immersion, contact or phased array probes.

They make it possible to solve new inspections while keeping a high level of acoustical performances

The main specialties of these probes are :

• Particular geometry to match the inspection setup
• Use of advanced piezocomposite material to reach particular electroacoustical performances ( power, bandwidth, sensitivity..)
• Integration of electrical impedance matching  or electronic components (multiplexors, preamplifiers, ...)
• Adaptation to harsh environmental conditions (temperature, pressure, nuclear radiation...)
