SpectraSwitch™
Multi-Spectrum Imaging
The world's first and only triple-mode ductoscope imaging system — white-light HD, UV 365/405 nm fluorescence, and thermal/IR in a single probe. No other ductoscope on the market combines all three. Switchable in the field without removing the probe.
HD White-Light
High-definition CMOS imaging with bright white LED illumination. Reveals structural conditions, debris accumulation, corrosion, and mechanical damage in full color.
- Full-color HD imaging
- Structural integrity assessment
- Debris and contamination mapping
- NADCA-compliant documentation
UV Fluorescence
Dual-wavelength UV at 365 nm and 405 nm excites fluorescent compounds in biofilm, mold, and organic residues — making invisible contamination visible.
- 365 nm + 405 nm UV wavelengths
- Biofilm colony detection
- Mold and fungal mapping
- Post-remediation clearance verification
Thermal / IR
Integrated thermal array sensor detects temperature differentials as small as 0.05°C — revealing moisture, water leaks, and thermal anomalies invisible to any optical camera.
- < 0.05°C NETD sensitivity
- Water leak detection
- Moisture intrusion mapping
- Thermal anomaly documentation
The Contamination You Can't See is the Contamination That Matters Most
White-light inspection reveals what is visible — debris, dust, structural damage. But the most serious contamination threats in HVAC systems are invisible under standard illumination.
Biofilm colonies — the precursor to mold amplification and Legionella growth — appear as clean metal surfaces under white light. UV fluorescence at 365 nm makes them glow with unmistakable fluorescent signatures.
Water intrusion — the root cause of most mold events — is invisible until structural damage appears. Thermal imaging detects moisture differentials before any visible sign of damage, enabling proactive intervention.
