FLIR Si2-Pro Key Features:
✅ All-in-One Detection:
- Find electrical faults (partial discharges) in high-voltage equipment
- Detect compressed air and gas leaks from up to 200 metres away
- Spot mechanical faults, such as worn or failing bearings
No need to carry extra devices—the FLIR Si2-Pro does it all in one simple unit.
✅ Save Time and Money:
The FLIR Si2-Pro helps prevent unplanned breakdowns by spotting problems early. Finding leaks and faults before they get worse saves you energy, reduces repair costs, and helps avoid costly downtime.
It also shows how much air or gas is leaking and estimates how much it‘s costing you—so you can prioritise repairs and boost efficiency.
✅ Smart On-Board Analysis:
The FLIR Si2-Pro gives you more than just images—it helps you understand what’s going wrong. It can:
- Automatically identify the type of partial discharge
- Rate the severity of each problem
- Record and save inspection data
- Connect to the cloud for easy sharing and tracking
- Get software updates over the air (OTA)
✅ Easy to Use and Built to Last:
The FLIR Si2-Pro is made for busy technicians and engineers. It’s lightweight and designed for one-handed use, so you can work comfortably all day. It features:
- 12 MP camera for clear visuals
- 8x zoom to focus on distant targets
- Automatic frequency tuning for clearer detection
- IP54 rating for protection in harsh environments
- Built-in QR code scanner for quick asset tracking
