Ionix offer a range of accessories to facilitate accurate, fast and reliable on-stream ultrasonic testing. From detachable guards and port inspection wands to protect the user, to abrasion resistant, heat resilient cabling and ultrasonic couplants suitable for a range of extreme environments.


High quality, heat and abrasion resistant dual UT cables to connect the probe to any thickness gauge or flaw detector using compatible connectors. All cables are temperature resilient, co-axial cables protected using a fiberglass outer jacket for continuous use up to 250°C (392°F) or intermittent use up to 550°C (1022°F) without conducting heat to the user. The cables are compatible with all the handle extensions, including the 2” handle and strain relief.

  • The fiberglass outer jacket provides heat and abrasion resistance to the cable assembly without impacting flexibility and keeping it lightweight.
  • Fiberglass, as opposed to a flexible metal conduit, prevents conduction of heat through the cable reducing risk of burning the operator or damaging equipment.
  • The cable uses common connectors to allow integration to all thickness gauges and flaw detectors with options for gauge specific connectors and identification pins for common commercial gauges from Evident, Waygate and others.


  • For use with dual probes for thickness, corrosion, erosion surveys and TOFD probes for weld inspection.
  • Ideal for scanning application where a robust, lightweight cable option is required.

Thickness gauging and corrosion mapping is often conducted in-service at temperatures exceeding 100°C (212°F) where not only can the couplant degrade, evaporate, or vaporise, but also reach the temperatures at which autoignition can occur. Ionix supply a range of couplants from Echo Ultrasonics for temperatures above 150°C (302°F) which offer high temperature stability, low corrosion characteristics, low toxicity, and smoke, and have clear indication of their auto-ignition temperatures.



  • Gels or pastes with different viscosities for all applications.
  • Couplants for all measurement applications from -45 to +675°C (-50 to +1250°F).
  • Provide strong signals and fast response measurements across a broad range of temperatures.
  • Non-toxic with low smoke and no residue options available.
  • Options which meet ASTM F519 and offer long-term corrosion resistance and inhibition.
  • Low viscosity options for scanning, by request.


  • All thickness measurements from -45 to +675°C (-50 to +1250°F).
  • Scanning applications with low viscosity products.

Detachable handles to extend the reach of the HotSense™ UT probes to provide extra grip when wearing PPE and protect the user from extreme temperatures. Specifically designed to make port inspections easier and safer. The handles are simply screwed on to the back of the ultrasonic transducer using the integrated threads. Probes maybe switched between handles providing versatility across different applications. Optional strain relief on the 2” handle has a sealing gland which clamps around the cables to provide additional protection from water, couplant and debris ingress to the probe connector. Ideal for hand held use or automated scanning.



  • Extend the reach of the UT probe to protect the user from extreme temperatures and for making port inspections.
  • Provides additional grip when handling the probe whilst wearing personal protective equipment (PPE).
  • Protects the cable and probe connections from mechanical damage.
  • Strain relief with 2” handle prevents water and dirt build up at the back of the probe.
  • Light-weight with knurled surface to enhance grip.
  • Hot swappable to adapt handle length as required for the application.
  • Compatible with all standard, non-armoured cables.


  • Any extreme environment, or high-temperature spot or grid measurement.
  • Ideal for port inspections.
  • 2” handle and strain relief provide connector protection and cable lift off during probe scanning.
  • 6” and 12” handles are ideal for ultra high-temperature (>350°C / 662°F) measurements.
