The FLIR Si1-LD is a state-of-the-art industrial acoustic imaging system specifically designed for the detection of compressed air and vacuum leaks. With an impressive detection range of up to 130 meters, this model is ideal for large industrial facilities and demanding environments.
Thanks to the innovative noise suppression technology, the camera enables reliable leak detection even in noisy environments. The combination of real-time leak rate and cost analysis, intuitive one-handed operation and lightweight design makes the FLIR Si1-LD an indispensable tool for preventive maintenance, energy savings and regulatory compliance.
It is particularly suitable for applications in the manufacturing industry, process industry and energy efficiency programs.
