Full 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. Areas of application of the testo 872 thermal imager Detect locations at risk of developing mould, pinpoint thermal bridges, discover structural defects or identify overheated connections. The testo 872 thermal imager is ideal for applications in daily maintenance and installation work in trade and industry. Quick, simple and reliable for maintenance and detection of defects. Technical highlights of the testo 872 thermal imager The testo 872 thermal imager is characterized by its easy handling and its outstanding image quality. Its technical features are impressive: • Highest image quality thanks to high resolution: 76,800 temperature measuring points for precise thermography. Infrared resolution of 320 x 240 pixels – extendible to 640 x 480 pixels via integrated SuperResolution Technology • Detecting temperature differences from as little as 0.05°C • testo Thermography App to use mobile terminal devices as a second display and for remote control or to write and send reports, along with saving them online • Wireless communication thanks to Bluetooth – this means you can also wirelessly integrate the readings of the compatible testo 770-3 clamp meter and testo 605i thermohygrometer • Built-in digital camera generates a real image in parallel to the thermal image • Integrated laser marker – can also be precisely visualized as a measuring point in the thermal image • 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, for example 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 • Pro software for image evaluation on the PC • You can choose to save thermal images as JPEGs Key benefits: • Highest image quality: IR resolution of 320 x 240 pixels, via integrated testo SuperResolution Technology 640 x 480 pixels • Precise measurement: thermal sensitivity of 0.05°C • Smart and wireless: use your mobile device with the free testo Thermography App and wirelessly transmit readings from the testo 770-3 clamp meter and the testo 605i humidity measuring instrument (both available separately) • Integrated laser marker – can also be precisely visualized as a measuring point in the thermal image Install the free testo Thermography App on your smartphone/tablet and take advantage of these practical functions: • Create reports, save them online and send them by email • Incorporate additional comments and measuring points in a thermal image, determine temperature progression via a curve • Transmit thermal images live to your smartphone/tablet and use this as a second display Image quality with IR resolution of 320 x 240 pixels (with testo SuperResolution technology 640 x 480 pixels) Scope of delivery: testo 872 thermal imager with radio module for Bluetooth/WLAN, USB cable, mains unit, lithium-ion rechargeable battery, pro software IRSoft (free download), 3 x testo ε-Markers, commissioning instructions, short instructions, test protocol and case.
