Gloss Levels Measured
ISO2813 recommends surfaces measuring mid to low gloss finishes using 60° and 85°. Is the Flex 20 suitable or measuring these surfaces?
60° and 85° give greater resolution of measurement at these gloss levels (small visible differences in finish = a large difference in gloss value).
Whilst 20° has a smaller measurement resolution, visible differences in gloss can be quantified with the Flex 20.
The measuring head should only be connected to the instrument for measuring larger flat surfaces. It is recommended to connect the instrument to the measuring head using the cable for ease and stability of measurement.
