Specialist Surveys - Infra-Red Thermography Inspection


Heat is often an early symptom of equipment damage or malfunction, making it a key performance parameter monitored in predictive maintenance. Infrared predictive maintenance regularly checks the temperature of critical equipment, allowing tracking of operating conditions over time and quickly identifying unusual readings for further inspection.

Infrared thermography inspection is perceived as the most effective faults diagnosis technology, utilizing thermal imaging cameras to produce thermal images (immediately and clearly visible) of invisible infrared or “heat” radiation caused by electrical resistance and mechanical wear based on temperature differences between objects.

With our Infra-Red Thermography Inspections you can:

  • Accurately pinpoint problems which can lead to a 10-fold return on investment
  • Prevent expensive failures thus reducing maintenance costs by 25% to 30%
  • Improve efficiency thus eliminating breakdowns by 70% to 75%
  • Reduce non-productive downtime by 35% to 45%
  • Avoid shutdowns and lost revenue which could increase production by 20% to 25%


A Thermal Imaging Camera is a reliable, non-contact instrument for monitoring and diagnosing, which is able to scan and visualize the temperature distribution of entire surfaces of objects or equipment quickly and accurately. A FLIR T-420 Infrared Camera measures up to -4°F to 1202°F (-20°C to 650°C).
