Thermal Imaging – Never sleeps. Sees everything.

The many uses for thermal imaging

Thermography can be used for a plethora of different assignments. From detecting mechanical abnormalities to preventing dampness build up, thermal imaging cameras really are the key to both good maintenance and avoiding downtime. Below is a breakdown of some of the common tasks and industries thermography is useful for:


Easy monitoring of heating and installation systems



Thermal imaging can be used to check heating, ventilation and air conditioning systems. You can pinpoint any irregularities to the temperature distribution right away, so it’s easy to locate clogged radiators and leaks. Testo thermal imaging cameras are both accurate and easy to operate, so are ideal for such tasks.


Typical applications include:

  • Pinpointing the course of heating loops in an underfloor heating system
  • Checking radiators for the build-up of deposits
  • Measuring the supply and return temperature
  • Locating leaks


Checking as part of electrical maintenance


Increased temperatures of electrical appliances and cables are often either an indication of an overload, an imminent malfunction, or an existing defect. Thermographic images lead to the early detection of such issues. This way the necessary preventive measures can be introduced in a targeted way. Using thermography for maintenance both minimises risk of fire and prevents costly production downtimes. Testo thermal cameras are perfect to uncover problems early and can be used to evaluate the heat status of low, medium or high-voltage systems.

Typical applications include:

  • Checking switch cabinets
  • Checking electrical connections
  • Monitoring and checking photovoltaic systems
  • Checking as part of mechanical maintenance


Detecting structural defects and ensuring construction quality


Thermal analysis is an efficient method of detecting possible structural defects. Furthermore, Testo thermal imagers are ideal for providing proof of the quality and the correct implementation of construction measures. Any heat losses, humidity and areas of air permeability in a building are visible in the thermal image. This makes it possible to detect faulty thermal insulation and structural damage – all using a non-contact method!

Typical applications include:

  • Checking the air tightness of windows and doors
  • Finding insulation defects and thermal bridges in the building shell
  • Detecting areas which are prone to mould


Locating leaks in flat roofs


Damp areas in the roof structure, in particular in flat roofs, store the warmth from the sun for longer than intact areas. This means as the sun goes down the roof structure will cool unevenly. Testo thermal imaging cameras expose temperature differences to pinpoint the exact roof areas with trapped moisture or damaged insulation.



Checking as part of mechanical maintenance


Signs of wear in machinery often become apparent long before a malfunction, due to an increase in temperature. Possible causes are friction, incorrect adjustment, tolerances of mechanical components or a lack of lubricant. Thermal imaging can help to detect suspicious changes before they become a problem. A key advantage of using thermography in a maintenance operation is that it’s non-contact, and can therefore be carried out on all mechanical installations during operation and from a safe distance.

Typical applications include:

  • Checking engines
  • Checking bearings
  • Checking shafts


Carrying out energy consultation


Thermal imaging cameras are ideal for quick and easy visualisation of energy losses in the heating or air conditioning systems of buildings. Thermal imagers are ideal for recording and documenting energy losses on outer windows and doors, roller blind casings, radiator niches, roof structures, and also the entire building shell.

Users can therefore make a comprehensive diagnosis to analyse energy efficiency, to plan for potential structural improvement measures. Thanks to their high temperature resolution, Testo thermal imagers provide a detailed presentation of inadequate insulation and thermal bridges in the building shell.

  • Detailed energy consultancy
  • Analysing building shells
  • Easy to use in conjunction with Blower Door


The adoption of thermal imaging technology will lead to cost savings in a number of ways; through reduced maintenance hours, increased operating efficiency, and more effective operation of maintenance engineers. Whether you’re looking at heating, mechanical machinery, dampness, electrical appliances, or building structures, thermal imaging really is an excellent means of conducting analysis.

  1. As more and more people realize the great potential of this imaging technology, thermal cameras are being used today in many applications and many different ways. In many countries worldwide, thermal cameras play pivotal roles in a wide range of government, commercial, and industrial activities.

    best uses of thermal camerasSince temperature is used for many applications and it is very important in our everyday lives, thermal imaging cameras can be used in many ways and for many applications. They take measuring temperature to the next level, showing a picture with temperature differences of a surface instead of getting a number for the temperature.

    Thermography or thermal imaging, with the use of a thermal imaging camera produces an image of invisible infrared light emitted by objects. This technique provides rapid scanning of a surface that is environmental friendly and nondestructive, allowing for quick detection of potential defects or problems. This way it can be reduced the need for preventive maintenance and the troubleshooting time.
    Thermal Camera Applications

    In home inspection industry, thermal imaging cameras are becoming a common tool and are being used to locate leaks, determine insulation condition, locate moisture intrusion, verify building performance to specifications, and verify structure design. Thermal cameras can be used in the thermal patterns to help to diagnose a condition, such as an overload electrical circuit or poor insulation in a home. Other thermal imaging camera uses include:

    Radiant heat location in wires or pipes
    Thermal heat loss inspections of buildings
    Detect insulation leaks in refrigeration equipment
    Substation electrical inspections
    Detecting leaks on flat roof buildings
    Locate potential areas for mold growth
    Mechanical bearing inspections
    Thermal pattern detection on boiler tubes

    Depending on your specific application, you may need more sophisticated camera features such as:

    A picture-in-picture feature that displays a color thermal image inside a standard digital image.
    A color alarm feature that allows the user to select a temperature.
    A blending or fusion feature that allows the user to blend within a standard digital image either the minimum, maximum, or average temperature of the thermal image.

    In order to use thermal imaging cameras in the best ways you need experience and knowledge in interpreting the captured image. Thermal cameras usually feature four adjustments in order to help a user obtain the best thermal image to analyze: emissivity setting changes, focus, thermal tuning, and reflective temperature setting changes.
