Introduction
Thank you for choosing the optris® S20 infrared sensor.
Infrared thermometers measure the object surface temperature without touching it.
They calculate the surface temperature on the basis of the emitted infrared radiation
from an object. The most important feature of infrared thermometers is that they
enable the user to measure objects contactless. Consequently, these products help
to measure the temperature of inaccessible or moving objects without difficulties.

Optical Charts
The following optical charts show the diameter of the measuring spot in dependence
on the distance between measuring object and sensing head. The spot size refers to
90 % of the radiation energy.
