• Designed for hazardous Zone 2 areas, and provides ATEX-certified safety
• Detects multiple gas types, pressurized gas leaks, and partial discharge
• Phase Resolved Partial Discharge (PRPD) for discrimination between different types of partial discharge
• Analyze waveform, spectrum, spectrogram, leakage assessment, discharge type discrimination
• IP54 rating; Wide operating temperature range from -20 to 50 degrees Celsius

The MPAC128-ATEX is designed for hazardous Zone 2 areas and provides ATEX-certified safety without compromising performance. Identifying gas, pressure, and vacuum leaks, as well as corona, arcing, and partial discharge faults up to 120 meters away, including challenging areas, this model ensures prompt action to restore safety and system integrity in finished products, process plants, and electrical installations. The MPAC 128-ATEX quipped with 128 sensors, this high-resolution acoustic imager

The MPAC128 series also packs impressive reliability with the units ingenious self-check function, meticulously verifying internal components’ integrity and guaranteeing flawless operation of the microphone array, providing unwavering performance day in, day out.

Megger MPAC128 and MPAC128-ATEX are hand-held professional acoustic imagers that support both audible and ultrasonic frequencies. The MPAC128-ATEX features a II 3G Ex ic IIC T5 Gc explosion-proof rating.

The cameras use microphone array beamforming technology to acquire, measure and visually display the sound source data, overlaid on a real time high definition video image. By integrating the sound source data with the video image, the changing sound source is dynamically displayed on the screen in the form of a “sound map”.

Both the MPAC128 and MPAC128-ATEX Professional Acoustic Cameras aid the detection of air or gas leaks in both compressed and vacuum systems, even in noisy industrial environments. When used in power systems, they can help to safely and quickly identify partial discharge where dielectric breakdown is occurring.

The cameras are designed and built for use in industrial applications where both moisture and dust may be encountered, with the case built from a strong and durable machined aluminum alloy.

The instruments are simple and convenient to operate. They require adjustment of only two parameters: the measurement frequency range and the dynamic range. They offer both picture and video capture modes, making data recording easy and flexible. Test results can be downloaded from the removable microSD card, or via the USB-C port, to allow for analysis and report generation.

Please ensure all the safety warnings within the user manual are read and understood before operating the cameras.
