– Significantly reduce unscheduled power outages– Detects problems quickly, without interrupting service– Assess priorities for corrective action– Minimize preventive maintenance and troubleshooting
time– Improving Equipment Reliability & Life– Check for defective equipment while still under
manufacturer warranty.

High Definition Infrared
Higher resolution means sharper images
Higher resolution means better measurement accuracy at a
distance
640x480 = 307,000 detectors

Air Leaks
The camera does not “see” air, but it does see the
cooling effect of the cold air on the surface of nearby
materials

Important Notes
– Infrared inspection requires a sufficient difference in temperature from inside to outside (ΔT of 10°C) for a sufficiently long period of time, to produce discernible differences between areas with studs and areas that may contain insulation.
– Wet materials retain heat and change slower than dry areas of the same type building material.
– Knowledge of building construction is necessary to properly diagnose the problem.
Use IR thermography in conjunction with:– R-Value calculator and energy savings estimator– Dew point and wet spot location– Blower door testing– Duct leak testing
