Storage and Handling
This instrument contains precision optics and electronics. You should avoid
knocking or dropping the device as the resulting impact could cause serious
damage.
In some circumstances the optical components in the instrument could
become misted as a consequence of temperature change. It is recommended
that the instrument is not used until it has stabilised to the ambient
temperature.
Ensure that the instrument is not exposed to moisture, chemicals or any
corrosive vapours.
Do not interfere or place any objects inside the measuring aperture as damage
to the measuring system could occur.
The instrument housing and screen are resistant to a variety of solvents
however it is not possible to guarantee resistance to all chemicals, therefore

About the Rhopoint NG Flex 60
The Rhopoint NG Flex 60 is used to quantify the gloss of difficult to access mid-low
gloss surfaces. The instrument measures using the 60° geometry specified for
measuring mid gloss surfaces 10-70GU.
To improve the measurement performance on low gloss surfaces (0-10 GU) the
instrument has a GUh range: gloss unit high resolution. The GUh range gives x10
resolution and improved repeatability and accuracy on low gloss surfaces. Any
surface from 0-125 GU can be measured using this device.
The GUh low gloss high resolution range uses an additional high gain amplifier for
improved measurement on matt surfaces.
