The tool can be clearly identified with the serial number 2 on the type plate.
1) at an ambient temperature of 20–23 °C and an emissivity of >0.999, measuring distance: 0.3m,
operating time: >5 min.
2) limited performance at temperatures <0 °C.

Infrared heat radiation
Infrared heat radiation is electromagnetic
radiation emitted by every body. The amount
of radiation depends on the temperature and
the emissivity degree of the body.
Emissivity Degree
The emissivity degree of an object depends on
the material and the structure of its surface.
It states how much infrared heat radiation the
object emits compared to an ideal heat emitter
(black body, emissivity degree = 1).
Thermal Bridge
A thermal bridge is an object that undesirably
transmits heat outwards or inwards, therefore
differing significantly from the temperature
of the rest of a wall or from the desired
temperature of a wall.
As the surface temperature at thermal bridges
is lower than in the rest of the room, the risk of
mold increases significantly at these locations.
Reflected temperature/reflectivity of an
object
The reflected temperature is the thermal
radiation that is not emitted by the object
itself. Depending on the structure and
material, background radiation is reflected in
the object to be measured, therefore distorting
the actual temperature result.
Distance from the object
The distance between the object being
measured and the measuring tool influences
the captured area size per pixel. You can
capture increasingly large objects as the
distance from the object becomes greater.
