preview
Beijing Jeffoptics is pleased to
announce that it will, once again, be
exhibiting its products at Glasstec 2018, an
important occasion for Jeffoptics.
Right from the first exhibition, Jeffoptics
was well prepared and had on show its
JF-1E glass surface meter. From then on,
Jeffoptics has continued to create good and
solid connections with dealers and clients
around the world.
After two years of research and develop-
ment, Jeffoptics will show its JF-1 series,
JF-2 series, JF-3 series and the latest prod-
uct JF-4 series glass surface stress meters
this time at Glasstec 2018. Jeffoptics JF-1
series and JF3 series are for thermal tem-
pered glass surfaces stress measurement.
Both devices comply with ASTM C 1048,
ASTM C 1279, EN 12150-2, EN 1863-2.
JF-2 series and JF-4 serieas are for chem-
ical tempered glass surface stress measure-
ment, and comply with ASTM C 1422m.
There is no movement of components in
JF-2, the operator can have the result just
by putting the device on the surface of
chemical tempered glass.
Jeff Li, Chairman of Jeffoptics, always
says: “Jeffoptics’ products make measure-
ment easy, and we look forward to provid-
ing our clients with more accurate, efficient
and convenient tools”.
So we look forward to communicating
with visitors throughout the show this time
and Jeffoptics will continue to upgrade its
technology and improve its service quality
to meet clients’ needs and demands.
