Safety warnings
n
This device may be used by
children aged 8 or above
and by persons with re-
duced physical, sensory or
mental capabilities or lack of
experience and knowledge if
they are supervised or have
been given instructions on
how to use the tool safely
and understand the hazards
involved. Do not allow chil-
dren to play with the device.
Children are not allowed to
clean or carry out mainte-
nance work on the device
without supervision.
How it works
HL-Scan measures an object's surface tem-
perature. The heat radiation reflected from and
passing through the object is detected by the
tool's sensor. This information is then convert-
ed into a temperature reading. Emissivity is a
value used to describe the relative ability of a
material to emit thermal energy by radiation
(characteristic "radiance").

The higher the emissivity, the more capable
the material is of emitting thermal energy. Most
organic materials and surfaces have a emissiv-
ity coefficient of approx. 0.90. Metallic sur-
faces or shiny materials have a lower emissivi-
ty coefficient. HL-Scan's emissivity can be se-
lected so as to rule out imprecise measured
values.
