Thermal Imaging Hampshire

With our Flir thermal imaging cameras we carry out electrical and mechanical thermal imaging in Hampshire.

Preventative maintenance with

Thermal Imaging Inspections

Heat is one of the components of the fire triangle and when combined with oxygen and a source of fuel will cause a fire. Heat can be transferred through conduction, convection and radiation to flammable materials which if heated enough are then able to ignite resulting in fire. Heat cannot always be seen or sensed and from a health and safety perspective can pose a risk of burns and injury to persons touching something that they did not expect to be hot. Electricity is another common cause of fires in the workplace, overloading, poor connections and incorrect fuse ratings can cause cables and components to get hot. If undiscovered these components will become damaged, fail or catch fire. Fires in distribution boards, switchgear and machinery can cause major business interruption whilst the damage is repaired. Thermal Imaging inspections provide a cost effective way of carrying out preventative maintenance to identify and rectify issues before they become a problem.

Three phase fuse holder.FLIR0164

3 Phase Service Head

This shows a typical three phase electricity supply at its point of income into a building. The three small boxes are fuse carriers and contain a fuse for each phase. As can be seen the first fuse carrier is significantly hotter than the other two.

Industrial Oven

This image shows one of several large walk-in industrial ovens. These ovens are fairly old and over time the door seals and insulation has started to degrade and break down. The bright yellow line around the door shows heat leakage due to degradation of the door seal. The patchy orange areas around the edges and on the sides show where the insulation is damaged and where heat is being conducted through to the external walls. See below for a breakdown of the risks and issues in this image.


What is Thermal Imaging?

Thermal Imaging cameras use an infrared detector to simultaneously measure thousands of temperature points. These temperature points are then assigned a colour based on their temperature, normally cooler colours like black and blue and assigned to colder temperatures and lighter colours such as yellow, orange and red to hotter termperatures.

How does it work?

Thermal Imaging cameras use optical lenses to detect incoming infrared radiation which is then processed and displayed as a thermopraphic picture. This picture contains radiometric data which can be analysed to provide both qualitative and quantitative data. 

Our Thermal Imaging cameras measure and provide 76,800 unique temperature measurements in each thermal image. Analysis of these images can provide a wide range of information ranging from immediate risks to areas that should be focus to preventative maintenance.


  • Non contact – we do not have to touch the items that we are surveying.
  • No shutdown required. We are able to survey assets whilst they are up and running. There is no requirement to shut them down.
  • Inspections often reveal problems in the initial stages. This allows them to be remedied before components fail and cause fire or business downtime.
  • Accurate – our cameras measure to a fraction of a degree.
  • Surveying equipment that is not PAT Tested – there are a wide range of items such as server racks and three phase equipment that are never subjected to electrical testing because it is often impractical to shut them down. Thermal Imaging surveys can often pick up problems that have in the past gone unnoticed.
  • Condition Monitoring – Thermal Images can be compared to previous images to check for signs of deterioration and to allow maintenance to take place at a scheduled time.
  • Compliance – we can supply fully detailed thermal imaging reports to demonstrate your compliance.
