Product Description

The testo 872 thermal imager is ideally suited for professional industrial and building thermography - at the same time it ensures your work is both quick and easy. It is versatile to use, for example in industrial and mechanical maintenance or for detecting structural defects. You can generate error-free and objectively comparable infrared images using its handy functions. The IFOV warner, testo ɛ-Assist and testo ScaleAssist mean you can avoid measurement errors and not only effortlessly achieve optimum setting of emissivity (ɛ) and reflected temperature (RTC) for building thermography, but also of thermal image scale.
 

The testo 872 thermal imager– smart and networked

The testo 872 thermal imager guarantees wireless communication with mobile terminal devices via WLAN. The testo Thermography App for iOS and Android offers you the possibility of writing and sending reports on site, as well as saving them online, and of using your smartphone or tablet as a second display or for remote control.

The testo 872 delivers even more informative thermal images in combination with the compatible 770-3 clamp meter and testo 605i thermohygrometer. Both are available separately – simply order them straight away along with your testo 872. The thermal imager wirelessly integrates the measurement results of these measuring instruments via Bluetooth. The additional output, current and voltage values of the testo 770-3 clamp meter enable better interpretation of measured temperatures. Measure the air temperature and humidity with the testo 605i humidity measuring instrument and easily detect locations at risk of developing mould using the special humidity palette in the thermal imager via the traffic light principle.

Detecting structural defects and ensuring building quality (also for images of the building shell)

Analysis with the Testo thermal imager is a fast and efficient method of detecting possible structural defects. Furthermore, the thermal imager is also ideally suited for providing proof of the quality and correct implementation of construction measures. Any heat losses, humidity and lack of air tightness arising in a building are visible in the thermal image. The Testo thermal imager offers the possibility of detecting structural damage and implementation defects in the thermal insulation – all using a non-contact method! The testo ScaleAssist function, which automatically ensures optimum setting of the thermal image scale, means you get objectively comparable thermal images of buildings. This makes correct assessment of structural defects and thermal bridges easier than ever before. Detecting insulation defects and thermal bridges in the building shell is one of the typical applications.

Carrying out detailed energy consultancy

In building thermography, infrared technology is ideally suited for the fast and effective analysis of energy losses in the heating or air conditioning of buildings. Thanks to its high temperature resolution, the thermal imager provides detailed images of inadequate insulation and thermal bridges. It is impressive in terms of recording and documenting energy losses on outer windows and doors, roller blind casings, radiator niches, roof constructions or the entire building shell. The thermal imager is the best measuring instrument for comprehensive diagnostic and maintenance uses and always a good choice when it comes to energy consultancy.

Support in preventive maintenance

Reliable early detection of damage to production-relevant systems is essential in order to guarantee the safety and reliability of the system and prevent costly downtimes. Problematic areas in electrical and mechanical production facilities usually become evident due to an increase in temperature of the affected components. You can use a thermal imager to detect critical heat conditions (known as hotspots) in your system directly during operation, therefore guaranteeing an additional bonus in terms of reliability. Typical applications for the thermal imager:
  • Quick location of hotspots in electrical installations
  • Detection of critical heat conditions in engines, shafts and bearings

Easy checking of heating systems and installations

Heating, ventilation and air conditioning systems can be quickly and reliably checked thanks to the easy and intuitive operation of the Testo thermal imager. Just a quick look with the thermal imager is enough to discover irregularities in temperature distribution. Thermography can therefore 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 silting
  • Measuring the flow and return temperature

Investigating moisture damage

Not every damp wall is caused by a faulty water pipe. Water can rise or penetrate due to faulty installation of rain and water run-off systems, causing wet walls. Moisture damage can also occur due to blocked drains or insufficient seepage. The thermal imager finds the cause of rising damp or penetrating rainwater straight away, thus preventing greater damage.

On the trail of a ruptured pipe

If a pipe rupture is suspected, the only solution left is often to break open entire wall or flooring areas. The thermal imager enables you to minimize damage and reduce costs, because you locate precise leaks in underfloor heating and other inaccessible pipelines. This avoids opening up walls and floors unnecessarily and considerably reduces the repair costs.

Preventing mould formation
 

Thermal bridges waste energy. Condensation can also form in these places due to humidity in the ambient air. As a result, mould develops in these areas with the associated health risks for the occupants. The thermal imager uses the ambient temperature and humidity, determined externally with the testo 605i Smart Probe, along with the measured surface temperature to calculate the value of the relative surface moisture for each measuring point directly in the measuring instrument. Mould formation is therefore shown on the display before it becomes visible: areas at risk are displayed in red, those not at risk in green. This makes it possible to introduce measures to prevent dangerous mould formation in good time - including in hidden corners and alcoves.
 

Testing the air tightness of new builds

If doors or windows are not correctly fitted, in winter cold air can enter or warm indoor air can escape. This results in draughts, increased ventilation heat loss and above all high energy costs. The combination of thermography and Blower Door has really proved its worth. This procedure involves creating a negative pressure in the building, so that cool outside air can flow into the interior of the building through leaky joints and cracks. A Testo thermal imager makes the detection of the leaks considerably easier here. Any leaks are located – before facings and fittings for the new build make repair work complicated and costly.
