SONOTEC developed the new SONAPHONE. The digital ultrasonic testing device combines novel sensors and software that can be operated intuitively for preventive maintenance. Broadband airborne and structure-borne sound sensors that detect ultrasonic frequencies from 1 to 152 kHz, pave the way for new domains of use. Using the SONAPHONE you can find and classify leaks in compressed air, gas and vacuum systems, analyze the condition of your machines and systems, detect partial discharges and check the function of steam traps and valves. The mobile handheld device is operated with a touchscreen like a tablet and is the ideal companion throughout the entire test procedure. Besides test values and spectrograms, it is also possible to store photographs, voice memos and comments relating to the measuring points. With only a few clicks, you receive a test report and can prove to management your contribution to energy efficiency and process optimization.
