SONASCREEN
Application field：
The handheld acoustic camera SONASCREEN generates acoustic images from both the audible and ultrasound frequency range. The device locates sound sources in real time and displays the results immediately on the screen. Furthermore, the camera provides audible feedback through industrial headphones. We make ultrasound audible and visible.
Advantages at a glance
- 72 sealed microphones (spiral array) for use in industrial areas
- Real-time acoustic results at 100 fps
- Wide frequency range: Up to 100 kHz for the detection of audible sound and ultrasound
- Acoustic feedback via industrial headphones
Features
- Integrated data acquisition and analysis software
- Handheld device with IP54 protection
- Integrated LED lights
- 8 configurable buttons for fast control
- Low weight and small size
Application
Leak Detection
- Broadband ultrasound
