  • High-quality 32° × 23° lens: The lens with its manual focusing enables a wide field of view and an ideal overview of the temperature distribution, along with precise focusing on the object being measured
  • Automatic hot/cold spot detection: Critical temperature conditions are directly displayed during thermography
  • Solar mode: The solar radiation value can be input into the thermal imager and stored with each thermal image
  • Pro software for image evaluation on the PC included. You can also choose to save the thermal images as JPEGs. Find out more about the software
  • Measuring range: -30 to +350 °C

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. With a thermal imager, any suspicious changes can be spotted immediately. The main advantage of using thermography in a maintenance operation: it is non-contact and can therefore be carried out on all mechanical installations during operation and from a safe distance.

Typical applications for the thermal imager:

  • Checking engines
  • Checking bearings
  • Checking shafts

Checking as part of electrical maintenance

In electrical installations or cables, increased temperatures are always an indication of an overload, an imminent malfunction or an existing defect. Testo thermal imagers facilitate evaluation of the heat status of low, medium and high-voltage systems. Thermographic images lead to the early detection of defective components or connections, so that the necessary preventive measures can be introduced in a targeted way. Thermography therefore minimizes dangerous fire risks and prevents costly production downtimes.

Typical applications for the thermal imager:

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

Detecting structural defects and ensuring construction quality

Analysis with a Testo thermal imager is a fast and 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. The testo 870 thermal imager makes it possible to detect faulty thermal insulation and structural damage – all using a non-contact method!


Typical applications for the thermal imager:

  • Checking the air tightness of windows and doors
  • Finding insulation defects and thermal bridges in the building shell
  • Detecting areas that 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 the roof structure cools unevenly in the evenings. Testo thermal imagers use these temperature differences to pinpoint the exact roof areas with trapped moisture or damaged insulation.

Carrying out energy consultation

In building thermography, thermal imagers are ideal for quick, easy visualization of energy losses in the heating or air conditioning systems of buildings. Thanks to their high temperature resolution, Testo thermal imagers provide a detailed presentation of inadequate insulation and thermal bridges in the building shell. Thermal imagers are ideal for recording and documenting energy losses on outer windows and doors, roller blind casings, radiator niches, roof structures or the entire building shell. Comprehensive diagnosis can therefore be carried out to analyze energy efficiency, and structural improvement measures can be initiated.

Detailed energy consultancy, where the whole building shell is analyzed for its energy loss, effectively indicates further possibilities for energy saving.

Typical applications for the thermal imager:

  • Analyzing building shells
  • Easy to use in conjunction with Blower Door

Easy monitoring of heating and installation systems

Testo thermal imagers are easy and intuitive to operate, so they are ideal for quickly and reliably checking heating, ventilation and air conditioning systems. A quick glance with the thermal imager is enough to discover irregularities in the temperature distribution. Thus, thermography can be used to easily locate clogged radiators and leaks.

Typical applications for the thermal imager:

 

  • 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
