Yes, see table. 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, visiblee 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 cable for ease and stability of measurement
