Image quality with IR resolution of 320 x 240 pixels (with testo SuperResolution technology 640 × 480 pixels)
Thermal sensitivity of 0.05 °C
Including the testo 605i thermohygrometer: real time transmission of the ambient temperature and relative humidity readings to the thermal imager
Visualization of mould-risk areas with traffic light colours
Automatic detection of hot and cold spots
Free analytical software for creating professional reports
The testo 872s thermal imager stands out thanks to its resolution of 320 x 240 pixels, a very high thermal sensitivity, numerous innovative functions, smartphone connection via the testo Thermography App and the best price-performance ratio of its class. In addition to this, it fits comfortably in the hand and convinces with intuitive operation in a modern tile look. For even more meaningful thermal images, the thermal imager testo 872s also integrates the measurement values of the clamp meter testo 770-3 as well as the thermohygrometer testo 605i via Bluetooth (both available as an option).
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 872s 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 -Assist and testo ScaleAssist mean you can avoid measurement errors and not only effortlessly achieve optimum setting of emissivity () 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 872s thermal imager – smart and networked
The testo 872s 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 872s specially for building thermography
Infrared resolution of 320 x 240 pixels = 76,800 temperature measuring points, the infrared resolution is extended to 640 x 480 pixels via integrated SuperResolution Technology
Detecting temperature differences from 0.05 °C
42° 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 872s 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 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
