GDAC65
GOLD
Handheld acoustic imaging device locates high-frequency sound sources such as gas leaks and partial discharges through a microphone array. Supports single/multiple/holographic modes and T-FFTD transient capture.
Can evaluate leakage rate and annual cost, support PRPD partial discharge diagnosis.
Support point and circle measurement, ACS holographic video, Wi Fi remote access, and QR code on-site marking.
Do acoustic imagers have precision indicators?
This device does not provide a single accuracy value similar to "± 1dB" because acoustic imaging relies more on frequency range, sound pressure dynamic response, and image overlay logic.
The device supports a broadband response of 2kHz-100kHz and can stably image in partial discharge and gas leakage scenarios.
What maintenance work can it be used for?
It is suitable for the following maintenance tasks:
Location and leakage rate assessment of gas leaks - display leak level, leak volume L/min, estimated annual cost
Analysis of PRPD spectra of partial discharge
Intermittent noise capture - through T-FFTD ® Transient mode
Sound source localization of vibrating or loose components
As long as the frequency of the sound source is within the response range of the device and there is a distinguishable sound pressure difference from the environmental noise, it can be effectively used.
Product Advantages
No reliance on experience judgment: The imaging results are intuitive, and even beginners can locate the sound source
On site analysis: Analyze audio and video images directly on the device without the need for a computer
Multiple storage methods: supports ACS holographic video MP4、 Single frame image
Remote Collaboration: Supports Wi Fi, FTP, and web control (IRExplorer)
No risk of data falsification: do not beautify the dB value, display the true sound pressure difference
Multiple sound source detection
Leakage assessment

Application scenarios
Industrial and electrical maintenance: Identify potential hazards such as electrical equipment overheating and wire short circuits to prevent equipment malfunctions.
Building and pipeline inspection: non-destructive testing of wall structural defects, thermal bridge leakage locations, and precise positioning of underfloor heating pipeline leakage points.
Security and fire protection: all-weather night vision monitoring, search and rescue of trapped personnel, and searching for fire sources in thick smoke.
