testo 845 with integrated
humidity module
For the first time, surface
temperatures with smallest
diameters can be measured
accurately at short and long
distances. The switchable optics
for far-field and close focus
measurement make this possible.
Far-field measurements are
carried out at an optical resolution
of 75:1. In this way, surface
temperatures can be measured
accurately even at great distances
from the object to be measured.
At a distance of 1.2 metres from
the object to be measured, the
measuring spot diameter is only
16 mm. A cross laser marks the
measuring spot exactly during
measurement.
During measurements at a short
distance from the object being
measured, the close focus optics
has a spot diameter of only 1 mm
at a distance of 70 mm. Two laser
points mark the spot exactly.
