The FOTRIC TD2e Acoustic Imaging Camera is a portable ultrasonic detection tool for identifying air and gas leaks, electrical faults, and mechanical irregularities in industrial systems.
It features a 64-element MEMS microphone array operating across 2–100 kHz, allowing detection of both audible and ultrasonic emissions with precise positioning up to 60 metres. Detected sources are visualised as an acoustic overlay on a 5 MP image with a 58° × 45° field of view.
The system includes Noise Suppression to minimise ambient interference and Peak Mode for targeting specific frequency ranges when locating multiple faults. A 1-second startup enables immediate use on-site.
Built to IP54 standards, the device supports continuous inspections with interchangeable batteries delivering over 3 hours per charge. The supplied kit includes two batteries and carrying accessories for field operation.
