Infrared Thermography

Infrared Thermography is a non-destructive testing method that detects the amount of infrared energy either reflected, transmitted, or emitted from an object.  This non-contact form of inspection detects temperature differences on the surface of components or structures.  This rapid and economic inspection method, along with highly trained personnel and site-specific tailored reporting software, makes this an invaluable asset for many applications.  IRISNDT utilizes multiple infrared thermography cameras and techniques to meet client requirements.

IRISNDT applies infrared thermography for:

  • Furnace heaters, including both internal and external refractory lined equipment
  • Steam-air decoking monitoring
  • Optical gas imaging (including the ability to detect most volatile organic compounds)
  • Electrical components
  • Tank level and flare inspections
  • Moisture intrusion and flat roof inspections


  • Rapid and economical
  • Highly reproducible
  • Site specific tailored reports
  • Data is stored for future comparison or audits
  • Rapid results and trending analysis
  • Systems are portable and battery powered
  • Non-intrusive and can quickly locate anomalies
  • Visual representation and real time data on each report


  • Physical space and access points are required
  • Direct line of site is required
  • Environmental conditions may compromise external inspections and cameras must be shielded from atmospheric conditions
