What is Thermography?
All objects naturally emit infra-red radiation in proportion to their surface temperature. Thermography is the technique of measuring the emitted radiation and displaying the information as a visual image.
Our state-of-the-art equipment measures the radiation from 490,000 points every second and displays the information as a TV picture. This can then be recorded for subsequent analysis and to provide a permanent record of heat loss and surface temperature.
With a temperature range of -30°C to 2000°C and a sensitivity of 0.05°C, there are very few applications beyond our limits!
By combining infra-red and computer technologies, we are able to produce thermograms (heat pictures) having up to 256 colours which clearly show thermal profiles and temperature measurements.
Our Service
Our thermographic consultancy service is designed to allow customers from all spheres of business to take advantage of the latest thermal imaging technology and the experience required to achieve the best results.
We are able to tailor our service to meet your requirements exactly, whether these are for a brief inspection to locate a leak on an underground heating main or a detailed research study. Even the method of presenting the results of the survey is adjusted to suit your needs - perhaps a detailed written report is required, or a real-time video recording or even computer enhanced composite thermograms!
Through ongoing research, new applications for the technique are being developed on a regular basis so please do not hesitate to call us if your particular requirements are not listed in this brochure. We would be pleased to discuss your specific application and we will give you an honest opinion on whether this technique is a viable solution to your problems.

Electrical Installations Faulty electrical switchgear and distribution systems often cause unplanned plant shutdowns and may also represent a fire hazard. Thermography is a powerful condition monitoring tool that allows defects to be detected at an early stage in their development enabling better maintenance programming and a reduction in down-time. Underground Pipework Thermographic inspection of underground heating mains will immediately reveal leaks and areas of defective insulation. This allows repairs to be carried out quickly and minimises unnecessary excavation and service disruption. |
Flat Roofs Thermography enables areas of wet or defective insulation within the roof structure to be detected quickly and accurately. This allows local repairs to be carried out with optimum speed and minimum cost, instead of replacing the entire area. Building Surveys Thermography is an excellent tool for monitoring the performance of building envelopes. The technique allows the measurement of 'U' values, detection of cold bridging, damaged insulation and the location of hidden services or structural members. These surveys are now often used as part of the commissioning procedure on new or refurbished buildings. |

Concrete Delamination A combination of thermography and the natural heating/cooling cycle allows areas of de-laminated concrete and de-bonded render to be detected. The great advantages of this technique are that it is carried out remotely and is non-destructive. Cold Storage / Cryogenic Containers Thermography enables us to detect insulation breakdown and ice formation within cold storage and chill rooms. If left undetected, these can frequently lead to structural failure. |
Process / Petrochemical Plant Regular thermographic inspection allows maintenance to be accurately planned and process control to be optimised. Typical applications include refractory linings, trace heating systems, pipe blockages and thermal profiling. Research & Development As an accurate method of non-contact temperature measurement, thermography can often be invaluable during research and development programs. |
