Description
Here is the complete English translation for the detailed information and technical specifications of the testo 871 thermal imager:
The testo 871 thermal imager allows for even more informative thermograms when combined with compatible measuring instruments – the testo 770-3 clamp meter and the testo 605i thermohygrometer. Both instruments are ordered separately, but you can order them together with the testo 871. Measurement results from both instruments are easily transferred to the thermal imager via a Bluetooth interface. Current and voltage values obtained from the testo 770-3 clamp meter help to better interpret the measured temperature values. The air temperature and humidity measured by the testo 605i thermohygrometer help to more easily locate areas at risk of mold formation thanks to the thermal imager’s special humidity palette, which uses a traffic light principle.
Application Areas of the testo 871 Thermal Imager
Locating leaks, accurately detecting thermal bridges and defects in building envelopes, identifying overheating connections, or analyzing mold damage. The testo 871 thermal imager is ideal for use in daily maintenance and installation work in construction and industry. It provides fast and reliable defect detection and technical maintenance.
Key Technical Specifications of the testo 871 Thermal Imager
A combination of unique ease of use with professional measuring technology: the testo 871 thermal imager boasts the following impressive technical characteristics:
- Very good image quality thanks to high resolution: 43,200 temperature measurement points provide highly accurate thermograms. The detector size is 240 x 180 pixels, and the integrated SuperResolution technology increases the resolution to 480 x 360 pixels
- Visualization of temperature difference from 0.09°C
- The testo Thermography App allows you to create reports right at the measuring site, save them online on your mobile device, and send them via e-mail, as well as use your mobile device as a second display or a remote control for the thermal imager
- Wireless connection via Bluetooth allows for the integration of measurement results from compatible measuring instruments – the testo 770-3 clamp meter and the testo 605i thermohygrometer
- The integrated digital camera captures a real image in addition to the thermogram
- Automatic hot and cold spot recognition allows you to see the critical thermal status directly on the display
- The testo ScaleAssist function automatically sets optimal temperature scale settings, allowing you to obtain error-free thermograms that are suitable for objective comparison, for example, when checking building airtightness
- The testo ϵ-Assist function ensures accurate measurement results by automatically determining and setting the values for emissivity and reflected temperature
- The IFOV warner function determines the distance to the measured object and the size of the smallest measurement spot that is shown on the thermogram. This allows you to avoid measurement errors, as the display shows you exactly what you can measure
- Professional software for image analysis on a PC
- You can save thermograms in JPEG format
