Thermal imaging is a technique that uses thermal imaging cameras to measure and visualize the temperature distribution of surface objects, buildings, installations or other structures. Principle of operation: Thermal imaging cameras record infrared radiation emitted by objects and convert them into a thermal image, which shows the distribution of temperature on the surface of the tested object. Each point in the thermal image is assigned a temperature value, which allows you to visually analyze the temperature distribution.

Thermal imaging applications:

  • Heat loss detection: Thermal imaging can be used to identify areas with inadequate thermal insulation in buildings. It allows you to detect where there is a heat leak, thermal permeability of walls, windows, doors, etc. This information is useful for taking corrective actions to improve the energy efficiency of the building and save costs.
  • Diagnosis of electrical installations: Thermal imaging is used to examine the condition of electrical installations, as overheating connections or components may indicate potential damage or a fire hazard. Early detection of such problems enables appropriate preventive actions to be taken.
  • Building Insulation Testing: Thermal imaging can be used to assess the insulation quality of buildings, both in new and existing constructions. This allows you to identify areas of low insulation that can lead to energy loss.
  • Moisture detection: Thermal imaging cameras can help detect moisture in walls, roofs, foundations and other building components. Detection of elevated temperature areas can indicate the presence of moisture or potential damage, allowing corrective action to be taken and more serious problems such as mold and material decay avoided.

We use TESTO 872s thermal imaging cameras to measure and visualize temperature distributions of surface objects, buildings or installations.

Camera characteristics:

  • High-quality thermal image: 76,800 temperature measurement points. Detector resolution 320 x 240 pixels, SuperResolution (optional) – 640 x 480 pixels
  • Visible temperature difference 0.05°C
  • Automatic Hot/Coldspot Detection: Critical points are displayed directly during measurement
  • With the testo ScaleAssist function, the scale of the image is adjusted with regard to the internal and external temperature of the measuring object as well as the difference between them. This guarantees obtaining comparable and error-free thermal images, e.g. maintaining the thermal insulation of buildings
  • The built-in digital camera generates a real image in parallel with thermal imaging
  • The IFOV Warner function allows you to determine the distance from the measurement object / measurement location
  • Professional thermal image evaluation software for PC
  • Ability to save the thermal image in JPEG format
