Acoustic imaging technology has transformed the way maintenance teams detect and locate leaks in compressed air, gas, and vacuum systems — and identify partial discharge in high-voltage electrical systems. Instead of scanning line by line with a handheld probe, you can now visualize sound in real time, pinpointing issues in seconds.
Fluke offers three powerful acoustic imaging cameras — the ii905, ii915, and ii500 — each designed for specific use cases and performance requirements. This guide will help you understand the differences so you can choose the right model for your needs.
Watch the video for a side-by-side comparison of each Fluke model in action.
The Fluke Acoustic Camera Lineup
Fluke offers three models to fit different facility sizes, budgets, and application needs:
- ii500 – Essential capabilities for facilities starting with acoustic imaging.
- ii905 – Mid-range performance with improved range and sensitivity.
- ii915 – Highest performance, designed for the most challenging environments.
All three cameras share Fluke’s rugged build quality, intuitive interface, and ability to detect leaks without shutting down equipment. The difference lies in detection range, sensitivity, and suitability for different working environments.
Fluke ii500 Acoustic Camera – The Essential Starting Point
The ii500 offers a cost-effective entry into acoustic imaging. It delivers accurate leak detection at shorter ranges and is ideal for facilities that want to move away from manual leak checks but don’t require extended detection distances.
Best for:
- Small to medium facilities
- Scheduled maintenance routes
- Teams new to acoustic imaging
Key features:
- Detects leaks in compressed air, gas, and vacuum systems
- Intuitive interface with minimal training required
- Compact, easy-to-handle design
Fluke ii905 Acoustic Camera – Extended Capability
The ii905 builds on the ii500’s capabilities with greater detection range and improved sensitivity, making it easier to find leaks in more complex or noisy environments.
Best for:
- Larger facilities
- Leaks located in overhead or difficult-to-access areas
- Energy audits where speed and accuracy matter
Key features:
- Greater stand-off distance for safer inspections
- Enhanced leak detection sensitivity
- Rugged design for industrial environments
Fluke ii915 Acoustic Camera – Maximum Range and Sensitivity
At the top of the range, the ii915 is designed for the toughest detection challenges. It offers the longest detection range and the highest sensitivity in the lineup, enabling technicians to locate even the smallest leaks from a safe distance.
Best for:
- Large industrial facilities with high ceilings and overhead piping
- Noisy environments where smaller leaks might be masked
- Quick inspections without disrupting operations
Key features:
- Longest detection range in the Fluke acoustic imaging family
- Highest leak sensitivity for early detection
- Ideal for preventive maintenance in mission-critical operations
Choosing the Right Leak Detection Equipment for Your Needs
| Feature / Model | ii500 (Entry) | ii905 (Mid) | ii915 (High) |
|---|---|---|---|
| Detection Range | Short | Medium | Long |
| Sensitivity | Standard | Enhanced | Maximum |
| Applications | Basic leak detection | Larger or more complex layouts | Largest, most challenging environments |
| Ease of Use | Easy | Easy | Easy |
Final Considerations
The right acoustic imaging camera can cut leak detection time from hours to minutes, reduce energy costs, and help meet compliance requirements. The ii500 gives you the essentials, the ii905 extends your reach, and the ii915 takes detection to the highest level.
