From HVAC cold spots to industrial heat processes, the Raythink RT630 handles temperatures from -20°C to 650°C, and up to 1500°C with an upgrade. Its smart auto-switching mode helps you stay efficient without needing manual recalibration.
🔧 Interchangeable Lenses
This camera adapts to your inspection needs:
- 25° standard lens for general use
- 7° telephoto for distant targets
- 45° wide-angle for cramped electrical spaces
- Macro lenses for fine details in R&D or electronics
Speedy and snappy performance.
📲 Smart Onboard Features
Powered by Android OS, the Raythink RT630 operates like a modern smartphone—with fast navigation, on-camera report generation, and built-in PDF creation. You can even email results directly from the field.
