Frequently Asked Questions
What is the difference between the Si2-LD, Si2-PD and Si2-Pro?
- Si2-LD – Optimised for compressed air & gas leak detection
- Si2-PD – Adds electrical partial discharge capabilities
- Si2-Pro – The advanced all-in-one model for multi-site maintenance teams
Can I detect both leaks and partial discharge with a single device?
Yes — the Si2-Pro supports both LD (leak detection) and PD (partial discharge) simultaneously, making it suitable for large plants, utilities, and multi-discipline reliability teams.
How far away can the Si2 detect leaks?
Depending on the model and environment, the Si2 can detect leaks up to 100 metres, thanks to its advanced 124–384-element acoustic array and long-range focusing.
Can the Si2 replace my thermal camera?
No. The Si2 is an acoustic imaging camera, not a thermal camera.
It visualises sound signatures such as:
• air & gas leaks
• electrical partial discharge
• mechanical anomalies
Thermal cameras remain essential for heat-related diagnostics.
What is the FREE C8 offer about?
During this promotion, every Si2 purchase includes a FLIR C8 Thermal Camera as a bonus tool for:
• quick thermal snapshots
• general awareness inspections
• maintenance documentation
The C8 is not intended to replace advanced industrial thermography.
