Ultrasonic Testing Device


In the age of Industry 4.0 the optimizing processes, increasing operational safety, and improving energy efficiency are becoming more and more significant. Meet the challenges of Maintenance 4.0 with the new SONAPHONE from SONOTEC. The digital ultrasonic testing device combines innovative sensors and software for preventive maintenance that can be operated intuitively and paves the way for new processes for new applications.

With the new SONAPHONE you can detect and classify leaks in compressed air, gas and vacuum systems and reduce your energy costs, monitor the condition of your machines and determine the optimal maintenance time, identify leaks in windows, doors, vehicles, components and containers and ensure compliance with specified quality requirements, find electrical partial discharges and insulation damage and increase your operational safety, assess the function of steam traps and prevent energy and steam loss and damage to the steam system. 


The mobile handheld device is operated with a touchscreen like a tablet and is the ideal companion throughout the entire test procedure – from planning, to measurement, to analysis. Store

to the test object. With only a few clicks you receive a test report and can prove management your contribution to energy efficiency and process optimization.

Depending on your requirements and applications, we offer you user-friendly software, innovative ultrasonic sensors and versatile accessories for your SONAPHONE.

Innovative sensors pave the way for new domains of use. While other ultrasonic testing devices can only find leaks, SONAPHONE can also be used to classify the leak size at the same time. Based on methods of aeroacoustics SONOTEC developed a completely new process for classification and evaluation of leaks. The result of the methods are plausible values for the classification of the leak size and for estimation of the savings potential.
