testo 890 – Thermal imager with super-telephoto lens

Description

The testo 890 Thermal Imaging Camera with Super-Telephoto Lens is a high-precision thermal imaging solution specifically designed for long-distance thermographic inspections. Featuring a 640 × 480 pixel detector (enhanced to 1280 × 960 pixels with SuperResolution technology), this thermal imager delivers exceptional clarity and accuracy, making it the ideal choice for professionals conducting inspections in power transmission, large-scale industrial sites, and solar energy systems. With a thermal sensitivity of < 40 mK, even the smallest temperature variations can be detected, ensuring highly detailed thermal analysis.

What sets this model apart is the 6.6° x 5° super-telephoto lens, which allows for the precise capture of extremely distant objects. This makes it an invaluable tool for applications where close access is not possible or unsafe, such as inspecting high-voltage power lines, identifying hotspots in expansive solar parks, and monitoring large industrial plants like refineries. The narrow field of view ensures that even the smallest connections and temperature differences at long distances can be thoroughly analysed with maximum resolution and precision.

This thermal imaging camera is essential for pinpointing hotspots in solar parks, which can indicate defective cells or faults in the system, as well as detecting irregularities in large industrial plants, such as refineries, where small temperature variations can be critical. The 6.6° field of view ensures that even the smallest details are captured with maximum resolution, enabling accurate and reliable inspections from a safe distance.

Included with the testo 890 Super-Telephoto Kit is a robust transport case, a memory card for image storage, and Testo IRSoft professional software for in-depth thermal analysis and reporting. With its high-resolution imaging, powerful long-distance capabilities, and cutting-edge thermographic features, the testo 890 with Super-Telephoto Lens is the ultimate solution for professionals requiring precise, long-range thermal inspections in demanding environments.
