Thermography - Limitations and Disadvantages of Thermography

Limitations and Disadvantages of Thermography

• Quality cameras often have a high price range (often US$6,000 or more)
• Images can be difficult to interpret accurately when based upon certain objects, specifically objects with erratic temperatures, although this problem is reduced in active thermal imaging
• Accurate temperature measurements are hindered by differing emissivities and reflections from other surfaces
• Most cameras have ±2% accuracy or worse in measurement of temperature and are not as accurate as contact methods
• Only able to directly detect surface temperatures
