testo 830-T4, non-contact temperature measurement on small surfaces at a large distance
The universal infrared
thermometer with 30:1 optics
makes it possible to measure
temperatures at a safe distance
from the object being measured.
The spot diameter at a distance
of 1 m is only 3.6 cm.
The 2-point laser marks the
diameter of the spot thereby
preventing areas outside the
object from being measured.
With a resolution of 0.1 °C, even
the smallest differences in
temperature can be detected and
dynamic temperature processes
analysed.
