What is SuperResolution?

SuperResolution is a blend of super sampling and deconvolution when viewed on a PC.

  • SuperResolution - takes multiple thermal pictures at .5 second intervals. The images are blended for 4x the pixel count.
  • Deconvolution - eliminates blurred images.

Both of these methods use the natural motion of your hand to create SuperResolution.

 *Not available on Mac. PC Only.

Precisely locating roof leaks

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.

Regular checks for electrical maintenance

Testo thermal imagers allow an 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 required preventive measures can be introduced in a targeted way. This minimizes dangerous fire risks and avoids costly production downtimes.

Hot on the trail of a ruptured pipe

If a pipe rupture is suspected, often the only solution is to break open entire wall or flooring areas. With Testo thermal imagers, you can minimize the damage and reduce the cost of your work. Leakages in underfloor heating and other inaccessible pipes are located precisely and without damage. This avoids opening walls unnecessarily and considerably reduces the repair costs.

Easy checking of heaters and installations

Testo thermal imagers can be used to quickly and reliably check heating, ventilation and air conditioning installations as they are easy and intuitive to operate. A check with the thermal imager is enough to discover irregular temperature distribution. Silting and blockages in radiators are reliably detected by using it.

Investigating moisture damage

Not every damp wall is caused by a ruptured pipe. Rising dampness or penetrating water due to rain and waste water drainage being incorrectly implemented can cause damp walls. Moisture damage can also occur due to blocked drains or insufficient seepage. Testo thermal imagers find the cause of rising dampness or penetrating rain water right away, before it can cause major damage.

Guaranteeing power generation

Energy is an important commodity that must always be available in sufficient quantities. For this reason, power stations and utility companies ensure that no interruptions occur, from power generation through to distribution. Testo thermal imagers support the preventive maintenance of electrical and mechanical components. This means developing damage is identified early.

Preventing mold formation

Thermal bridges waste energy. Condensation can also form in such places due to the humidity in the ambient air. As a result, mold forms in these locations with the associated health risks for the occupants. Testo thermal imagers use the externally determined ambient temperature and humidity as well as the measured surface temperature to calculate the relative surface moisture value for each measuring point. This means mold formation is shown on the display before it becomes visible to the naked eye: areas at risk are displayed in red, areas not at risk are displayed in green. This makes it possible to introduce measures to prevent dangerous mold formation at an early stage - including in hidden corners and niches.

Support in preventive mechanical maintenance

Reliable early detection of potential damage to production-relevant system components is necessary in order to guarantee the safety and reliability of machines. Heat emissions, especially from mechanical components, may indicate an elevated level of stress. This is caused, for example, by friction, faulty alignment, component tolerances or a lack of lubricant. With their high temperature resolution, Testo thermal imagers provide an exact diagnosis. Critical heat conditions can be detected directly using the alarm or isotherm function and preventive measures taken.

Finding structural defects and ensuring building integrity

Analysis with a Testo thermal imager is a fast and efficient method of detecting possible structural defects. Testo thermal imagers are also ideally suited 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. They also provide a method of detecting errors in the installation of thermal insulation and building damage – with no contact!

More reliability in quality assurance and production monitoring

Testo thermal imagers ensure precise situation analyses, thus supporting process control and product quality assurance. In addition to foreign bodies in production processes, anomalies in the heat distribution of components are also detected quickly at a glance and without contact.
