Thermography is the use of an infrared imaging and measurement camera to "see" and "measure " thermal energy emitted from an object.

Thermal, or infrared energy is light that is not visible because its wavelength is too long to be detected by the human eye; it's the part of the electromagnetic spectrum that we perceive as heat.

Infrared thermography cameras produce images of invisible infrared or "heat" radiation and provide precise non-contact temperature measurement capabilities.

Typical examples are;

• Preventive inspection electrical relays
• Functional check of air-coolers
• Monitoring the condition of reactors, ovens and furnaces
• Detecting problems with cooling of transformers
• Detecting hotspots in production plants
• Finding leakages in pipelines
• Shortcuts in electric processes
• Building insulation inspection

Special is the inspection of furnaces via the windows of the furnaces during operation. The inspection helps to analyze the individual functioning of the flame-pipes.

By using a special flame-filter the measurement of the temperature of the pipes will be accurate and not effected by the flames in the furnace.
