Use the smart testo 871 mould kit to detect mould-risk areas in buildings quickly and easily. The testo 605i thermohygrometer included in the kit transmits the room parameters via Bluetooth® to the testo 871 thermal imager. Mould-risk areas are shown in amber or red on the camera display (according to the traffic light principle). The thermal imager impresses with a thermal sensitivity of 0.09°C and its ease of use, in addition to its professional measuring cable with excellent image quality. The equipment can be transported safely and conveniently in the robust case.

Product Description

Incorrect ventilation behaviour or structural defects, such as thermal bridges, are some of the most frequent causes of mould formation in apartments, houses, old buildings and new builds. The testo 871 thermal imager and the testo 605i Smart Probe enable professional, simple and absolutely reliable detection of mould-risk areas before mould develops.

The professional thermal imager provides you with ideal support in your day-to-day work: 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 colour scale.

 

Special measuring mode for detecting mould-risk areas

Identify the risk of mould easily and reliably: the testo 605i thermohygrometer measures ambient temperature and humidity and transmits the readings in real time via Bluetooth to the thermal imager. The infrared camera measures the surface temperature and calculates the relative surface moisture using the readings from the thermohygrometer. The relative surface moisture is shown on the display as a humidity image – mould-risk areas are indicated using traffic light colours.

You can very easily see how big the risk of mould is by means of the traffic light colours (green, amber, red):
 
  • Green = no risk. The surface moisture is between 0% and 59% - mould spores do not find optimum growing conditions
  • Amber = caution, mould formation possible. The surface moisture is between 60% and 79% - some mould spores find optimum growing conditions
  • Red = attention, mould danger. The surface moisture is over 80% - mould spores find optimum growing conditions

 


The testo 871 thermal imager – smart and networked

The testo 871 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.
 
 

Technical highlights of the testo 871 specially for building thermography

 
  • Infrared resolution of 240 x 180 pixels = 43,200 temperature measuring points, the infrared resolution is extended to 480 x 360 pixels via integrated SuperResolution Technology
  • Detecting temperature differences from 0.09°C
  • 35° fixed-focus lens for a wide field of view and an ideal overview of the temperature distribution. The fixed focus means there is no longer any need for manual focusing
  • The testo Thermography App enables you to write reports on site, save them online and send them by e-mail, as well as allowing you to use mobile terminal devices as a second display or for remote control
  • Wireless transmission (via Bluetooth) of external measurement parameters, such as ambient temperature and relative humidity, from the testo 605i thermohygrometer to the testo 871 thermal imager
  • Critical temperature conditions are directly displayed via automatic hot-cold spot recognition
  • The testo ScaleAssist automatically ensures optimum setting of the thermal image scale, which means you generate objectively comparable and error-free thermal images, e.g. of the thermal insulation behaviour of buildings
  • The testo ɛ-Assist ensures the correct measurement result by automatically determining and setting the emissivity and reflected temperature
  • The IFOV warner means the distance from the measurement object / measurement spot size is determined and the measurement spot is shown on the thermal image – you therefore avoid measurement errors, because the camera shows you exactly what you can measure
  • For thermography of the highest possible standard, you need both a high-quality thermal imager and high-performance analysis software. The IRSoft software (free download) enables quick, easy and professional analysis of thermal and humidity images and their documentation in a report

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.
 

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.

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

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.

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.
