Flir Si1-LD Acoustic Imaging
- High-Performance Leak Detection - Detect Compressed Air Leaks
The Flir si1-ld is a cutting-edge Flir acoustic imaging camera designed to detect and quantify compressed air and vacuum leaks with speed and precision. It’s built for industrial use and offers high performance in a compact, affordable package.
This makes the Flir si1-ld ideal for maintenance, manufacturing, and engineering professionals looking to improve energy efficiency and lower operational costs.
Flir Si1-LD Key Features:
Accurate Leak Detection from a Distance
- Detect compressed air leaks from up to 130 metres with ultrasonic sensitivity across a 2–100 kHz bandwidth, enabling long-range inspections and safe stand-off in busy plants.
- The Flir acoustic imaging camera overlays sound on a visual scene to deliver a crisp digital image that makes leak paths obvious at a glance, supporting preventive maintenance.

Real-Time Quantification and Cost Analysis
- Instantly assess leak severity with live, on-device analytics that estimate leak rates and costs so you can prioritise repairs and save money.
Simple, Single-Handed Operation
- Lightweight, ergonomic design with an intuitive touchscreen makes the Flir si1-ld easy to use—ideal for fast inspections and preventive maintenance in loud industrial environments.
Advanced Acoustic Technology
The Si1-LD’s phased microphone array and signal processing deliver precise acoustic images with fine directional resolution, helping pinpoint leaks while suppressing background noise. Its long detection range supports large-area surveys without interrupting operations.
Each captured frame combines an acoustic map with a sharp digital image from the on-board digital camera for confident decision-making by maintenance teams using a Flir acoustic imaging camera.
Flexible Data Management and Reporting
Wireless or Direct Data Transfer
- Transfer inspections via Wi-Fi or USB—ideal for facilities that restrict network access.
Integrated Reporting Tools
- Use the Flir Acoustic Viewer cloud service for field analysis, or import findings to Flir thermal studio suite for offline editing, analysis, and advanced report creation—including templates for analysis and advanced report workflows and editing analysis and advanced refinements.
- Supports importing acoustic images for consolidated reporting alongside thermal and visual assets.
Ample Storage Options
- Local storage plus cloud workflows streamline collaboration and traceability across teams using an acoustic camera viewer cloud service.
Why Choose the Flir Si1-LD?
- Enhances plant efficiency by finding leaks that drive energy loss and higher OPEX—delivering measurable leak rates and costs to justify repairs.
- Supports sustainability reporting through quantifiable leak data from a Flir acoustic imaging camera.
