This document discusses thermography for measuring distant objects. It notes that measuring some objects requires maintaining a safe distance, and that high-resolution infrared imaging equipment is needed to detect important temperature differences and hot spots from far away. The solution proposed is using an infrared camera with a high-resolution detector and telephoto lens, like the Testo 890 camera. This allows creation of very high-resolution thermal images even at a distance, enabling precise thermographic analysis of remote objects.

Thermography
of distant objects
See all the details – even at a great distance.
Large distances to the measurement object require
either a reduction of the distance or superior technology.
In many situations, the measurement technology is the
solution: because faulty connections in high-voltage
masts simply cannot be examined from close up. Only
by using a very high-resolution detector and a high-
quality telephoto lens does one obtain the necessary
attention to detail in the thermal image at such distances
and can thus carry out meaningful analyses.

Thermography of distant objects We measure it.
The application
When “as close as possible” simply isn’t possible.
Whether it is the spatial conditions which prevent approaching the
measurement object, or the consideration of one’s own safety: a
user who cannot approach his measurement object close enough
needs to be able to rely on his technical equipment. In the
thermography of distant objects, all that helps, apart from telephoto
lenses, is a high-resolution infrared imager system. This is the only
way critical temperature differences and hot spots can be clearly
recognised and properly evaluated at a distance.
The solution
Simply stay away.
The basis for the exact determination of thermal irregularities at you can create extremely high-resolution thermal images in megapixel
great distances, e.g. in the cable connections in high-voltage masts, is quality. With the telephoto lens, you are guaranteed to recognise every
a high-performance detector. With the 640 x 480-pixel detector in the detail, even on far distant objects, with the testo 890, and can carry
testo 890 in combination with the new Testo SuperResolution technology, out precise thermographic analysis.
