2.5 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.
The distance is always measured from the front edge of the sensing head.
1.800.561.8187
optional (CompactConnect / IRmobile)
 5 °C and object temperatures >0 °C
The size of the measuring object and the optical resolution of the infrared thermometer
determine the maximum distance between sensing head and measuring object.
In order to prevent measuring errors the object should fill out the field of view of the optics
completely. Consequently, the spot should at all times have at least the same size like the
object or should be smaller than that.
