STCD is proud to announce their new partnership with Sonotec, a leading supplier of customer-specific Ultrasonic Applications and Technology, ‘Made in Germany’. This new venture with Ultrasound Technology broadens our offerings as your reliability partner.

The Ultrasonic Testing devices and sensors are used in a wide variety of industries including chemical, and mineral oil industries, mining, medical technology, pharmaceutical and the automotive industry.
Ultrasonic sensors and testing devices will help in detecting even the smallest leaks at an early stage in compressed air, gas and vacuum systems or pipelines that are hard to access. They are also suitable for valve testing and condition monitoring of machinery
They reliably inspect bearings, the functioning of valves as well as steam traps and detect electrical partial discharges on medium or high-voltage equipment. The SONAPHONE devices can also be used for tightness testing of cabins, hatch covers, containers and other pressureless systems. With the multi-purpose ultrasonic testing devices of the SONAPHONE family, many of these tasks can be carried out quickly and efficiently. 





The new SONAPHONE III extends the product range of SONOTEC with a digital ultrasonic testing device including touchscreen technology. This device for maintenance 4.0 is a hit with users thanks to apps that are intuitive to operate and opens up new domains of application in connection with innovative sensors. Learn More



The compact ultrasonic testing device SONAPHONE Pocket is characterized by an optimal price–performance ratio. The smallest testing device of the SONAPHONE family is intuitive to use and is applied primarily for leak detection on compressed air, gas and vacuum systems in preventive maintenance. Learn More



Due to its intrinsically safe construction, the SONAPHONE Ex is suitable for the use in the most hazardous areas and potentially explosive atmospheres. For maintenance staff on fixed offshore platforms, in petrochemical plants and other areas where a potentially explosive atmosphere may be present, the ultrasonic testing device is an essential part for numerous inspection tasks.
