Warning: To reduce the risk of injury to the eyes, do not look
directly into the targeting laser and do not point the targeting laser
into anyone's eyes. The instrument is equipped with a class II laser
that emits radiation.
Note: The pyrometer can measure objects at any distance but the object has to be
bigger than or at least as big as the spot size of the pyrometer in the measuring
distance.
Calculating the spot sizes on different measuring distances:
Spot sizes for other measuring distances can
be calculated with the following equations
or with the IR calculator of the InfraWin
software.
