Megger MPAC208 Acoustic Imaging Camera – See Sound. Find Faults. Save Energy.
The Megger MPAC208 is a next-generation professional acoustic imaging solution designed to transform the way maintenance teams detect, analyse and prioritise faults. As a powerful Megger MPAC Acoustic Camera, it enables you to see sound in real-time, pinpointing gas leaks, identifying mechanical deterioration and revealing partial discharge without interrupting operations.
Built around a high-performance 208-microphone MEMS array and advanced beam-forming technology, the Megger Acoustic Camera delivers fast, accurate localisation of ultrasonic sources across demanding industrial environments. From substations and switchgear to compressed air systems and rotating machinery, the Megger Acoustic Imager helps reduce downtime, cut energy losses and strengthen safety programmes.
MPAC208 vs MPAC208-IECEx
Both models deliver identical acoustic performance, imaging quality and analysis tools.
- Megger MPAC208 – Standard industrial model for general plant and utility environments.
- Megger MPAC208-IECEx – Fully certified for Class 2 explosive atmospheres, compliant with IECEx safety requirements for hazardous locations such as petrochemical and gas facilities.
Why Choose the Megger MPAC208?
At the heart of the Megger MPAC208 is a 208-channel microphone array operating across 2 kHz to 100 kHz. This wide bandwidth allows the Megger MPAC Acoustic Camera to detect extremely small leaks and subtle ultrasonic patterns that conventional tools often miss.
Combined with a 13 MP optical camera and a bright 8-inch capacitive touchscreen, the Megger Acoustic Camera overlays acoustic images directly onto live video. This makes sound sources instantly visible, allowing technicians to locate faults in seconds and make confident maintenance decisions.
With a detection range of up to 200 m, the Megger Acoustic Imager supports safe stand-off inspections in high-voltage or difficult-to-reach environments. Noise suppression and the intelligent Focus function isolate target signals even in loud plants, while SoundScan™ directional guidance helps locate sources outside the visible frame.
Designed for Real Industrial Environments
The Megger MPAC208 is purpose-built for utilities, manufacturing, renewables and heavy industry. Its lightweight 1.4 kg design, IP54 environmental rating and interchangeable smart batteries provide up to 10 hours of uninterrupted field operation.
Built-in diagnostics continuously monitor microphone performance, while the optional MPAC-V verifier allows fast on-site performance checks for frequency response, SPL accuracy and visual calibration.

Three Powerful Inspection Modes
Gas Leak Mode
Automatically estimates leak rate, distance and financial impact. The Megger MPAC Acoustic Camera displays sound pressure, volumetric loss and monetary cost so teams can prioritise repairs and recover wasted energy.
Partial Discharge Mode
With real-time PRPD visualisation, the Megger Acoustic Camera identifies and classifies discharge types without invasive testing. PD count and SPL readings help assess severity and support early intervention.
Mechanical Mode
Detect bearing wear, cavitation, valve leakage and vibration-related deterioration. The Megger Acoustic Imager provides time-domain, frequency-domain and spectrogram graphs for deeper root-cause analysis.
Thermal Correlation for Faster Diagnosis
When fitted with an optional thermal imaging module, the Megger MPAC208 delivers side-by-side acoustic and thermal overlays. This dual-modality view allows engineers to correlate heat and sound anomalies and confirm root causes more quickly.
❓ Frequently Asked Questions (FAQ)
Q1: Can underground gas leaks be detected?
A. No. Ultrasonic signals are absorbed by the ground and cannot reach the camera sensors.
Q2: Can liquid leaks be detected?
A. No. Liquid leaks usually do not produce detectable ultrasonic sound.
Q3: Can SF₆ leaks be detected?
A. No. SF₆ leaks are typically low pressure and do not generate sufficient ultrasonic emissions.
Q4: How often should calibration be carried out?
A. Calibration is recommended every two years. This interval may be extended if regular verification is performed using the MPAC-V verifier.
Q5: Which frequency range should I start with?
A. For general use, begin at 20–40 kHz. In quieter environments, use 15–35 kHz. In noisy plants, 28–48 kHz is recommended.
