Twin Element Ultrasonic Probe designed for high-temperature, in-service, wall thickness and corrosion surveys across oil and gas, refining, energy and process sectors. Great wear resistance allows for use on hot surfaces up to 300°C. Measures remaining wall thickness from 2.5mm to 50mm – depending on temperature and material.

Engineered to be used with the Cygnus 1 Ex ultrasonic thickness gauge, the High-Temperature Ex Probe can measure hot surfaces continuously without cooling, reducing inspection time and facilitating more effective measurement!

The probe is designed for use with a special probe cable wrapped in a glass-fibre outer braid to protect the cable.

The probe and probe cable are sold separately, enabling lower replacement costs.
