ABOUT THERMOGRAPHY

We exclusively use FLIR products, simply put they make the best infra red technology in the world, they’re technical back is second to none and they are nice people to work with.

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.

Lord Tim Bell (founder of Saatchi & Saatchi) advised us to form partnerships with ‘best in industry’ when we asked him how we could improve our market position.

How Do Infrared Cameras Work





An infrared camera is a non-contact device that detects infrared energy (heat) and converts it into an electronic signal, which is then processed to produce a thermal image on a video monitor and perform temperature calculations. Heat sensed by an infrared camera can be very precisely quantified, or measured, allowing you to not only monitor thermal performance, but also identify and evaluate the relative severity of heat-related problems. Recent innovations, particularly detector technology, the incorporation of built-in visual imaging, automatic functionality, and infrared software development, deliver more cost-effective thermal analysis solutions than ever before. Because thermal imaging technology works by identifying sources of heat and temperature differentials ie the temperature difference of roofing felt will show a temperature and the temperature of leaked water trapped under the felt will show a different lower temperature, finding leaks on buried/hidden cold water pipes cannot be found using a thermal imaging camera. To solve this problem where possible we will connect up the hot water pipe to the cold water pipe and allow hot water to flow through the pipe, FLIR cameras due there high sensitivity will then show where the hot water is leaking from the pipe work.

Infra Red Thermography is not x- ray, our equipment will not see through walls nor floors. However complex your problem please contact our office to arrange an appointment for a technician to call and discuss this with you.

CASE STUDY

The client had wet patches appearing on the ceiling below the photo of the roof area as shown below. On the right hand side of the thermal photo it is possible to just see the corner of some air conditioning equipment. Initially the client had called in an air conditioning contractor to inspect the equipment. The problem continued, a thermal imaging survey quickly identified the problem.



The Lighter yellow area shows where moisture has penetrated the felt roof covering and is leaking through to the building below. To the’ normal’ eye the roof area appears sound only a thermal survey can identify the problem quickly and efficiently. Upon closer inspection the water ingress was found to be caused felt delamination around the furthest vent pipe
