Testo 872 Thermal Imager

The testo 872 thermal imager stands out thanks to its resolution of 320 x 240 pixels, an excellent thermal sensitivity, numerous innovative functions, smartphone connection via the testo Thermography App and the best price-performance ratio of its class. 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 ?-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 thermal image scale. For even more meaningful thermal images, the thermal imager testo 872 also wirelessly integrates the measurement values of the clamp probe testo 770-3 as well as the thermohygrometer testo 605i (both available as an option). Testo ?-Assist: For precise thermal images, it is important to set the emissivity (?) and the reflected temperature of the object being examined in the imager. Previously, this was complicated, and with regard to the reflected temperature, less than accurate. This changes with testo ?-Assist: Simply attach one of the reference stickers included in delivery to the measurement object. Via the integrated digital camera, the thermal imager recognises the sticker, determines the emissivity and reflected temperature and sets both values automatically. FEATURES Infrared resolution of 320 x 240 pixels. Extendable with testo SuperResolution technology to 640 x 480 pixels. 76,800 temperature measuring points for precise thermography. Detect temperature differences from as little as 0.06°C. Built-in digital camera and laser marker. Testo ScaleAssist automatically ensures optimum setting of the thermal image scale. Testo ?-Assist ensures the correct measurement result. Save images as jpegs. Pro software for image evaluation on the PC.
