What is infrared surveying

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. Unlike visible light, in the infrared world, everything with a temperature above absolute zero emits heat. Even very cold objects, like ice cubes, emit infrared. The higher the object's temperature, the greater the IR radiation emitted. Infrared allows us to see what our eyes cannot.



Infrared thermography cameras produce images of invisible infrared or "heat" radiation and provide precise non-contact temperature measurement capabilities. Nearly everything gets hot before it fails, making infrared cameras extremely cost-effective, valuable diagnostic tools in many diverse applications. And as industry strives to improve manufacturing efficiencies, manage energy, improve product quality, and enhance worker safety, new applications for infrared cameras continually emerge.


How a thermographic survey offers considerable savings over conventional methods

Image Surveys offer the following distinct advantages over and above conventional survey methods:

  • Fast deployment
  • Primarily the equipment we use is extremely accurate, light and portable allowing faster deployment and more efficient surveying, thereby reducing costs in respect of overall time required.

  • Minimal disruption
  • The requirement for dismantling or disassembly of all forms of equipment, machinery, plant, switchgear, engines, systems and structures is almost eliminated during the actual survey process. This is due to Thermal Imaging producing a clear diagnosis of potential and actual problems via a clear real time image readout.

  • Greater accuracy
  • This in effect means that a greater number of potential and actual problems can be detected and diagnosed more easily and at an earlier stage. Reports generated using the equipment can be produced quickly and accurately.

  • Immediate results
  • Our trained operators can detect problems almost immediately via the electronic readout on the Imaging Equipment and a comprehensive report can be generated very quickly.

  • Undisputable results
  • The results of Thermographic surveys are legally accepted by the courts as well as by the Commercial and Insurance industries universally, where disputes and claims are involved.

  • Prevention before problems
  • Uniquely the equipment can detect problems and potential faults before they occur, therefore preventing and avoiding a great deal of expense and disruption.


The potential applications for our equipment are quite unlimited, however include the following:
