FLIR Si1-LD Acoustic Imaging
- High-Performance Leak Detection - Detect Compressed Air Leaks
The FLIR Si1-LD is a cutting-edge acoustic imaging camera designed to detect and quantify compressed air and vacuum leaks with unmatched speed and precision. The FLIR Si1-LD is great for industrial use. It offers high performance in a small and affordable package.
This makes it ideal for maintenance, manufacturing, and engineering professionals. They can use it 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 using a highly sensitive array of 96 MEMS microphones (2–100 kHz). The FLIR Si1-LD combines ultrasonic sensitivity with a 12 MP visual camera, 8× digital zoom, and LED lamp for superior image clarity.

Real-Time Quantification and Cost Analysis
- Instantly assess leak severity with live, on-device analytics. The FLIR Si1-LD calculates both the volume flow rate and annual cost of each leak, helping users prioritise repairs and report on energy-saving initiatives.
Simple, Single-Handed Operation
- Designed for ease of use, the FLIR Si1-LD is lightweight and ergonomic, enabling fast inspections with minimal training. Its intuitive touchscreen interface allows for quick navigation and real-time data interpretation—even in loud, industrial environments.
Advanced Acoustic Technology
The FLIR Si1-LD uses a 96-microphone array and sophisticated algorithms to produce precise acoustic images, even in challenging environments. Directional resolution starting from just 1° ensures pinpoint accuracy. Built-in automatic distance calculation and bandpass filtering allow users to focus on the correct frequency range, eliminating false positives from background noise.
Flexible Data Management and Reporting
Wireless or Direct Data Transfer
- Choose Wi-Fi, USB memory stick, or the optional direct data transfer cable—ideal for facilities that restrict network access.
Integrated Reporting Tools
- Use the FLIR Acoustic Viewer for cloud-based analysis or FLIR Thermal Studio for offline editing and custom report generation.
Ample Storage Options
- The FLIR Si1-LD features 32 GB internal storage and unlimited cloud backup for seamless data handling across teams.
Durable and Field-Ready
- Rated IP54 for rugged use, the FLIR Si1-LD is built to withstand industrial conditions. It includes all necessary accessories to begin inspections immediately: two batteries, charger, hard case, neck strap, and access to FLIR‘s software tools.
