The OMEGA® test gauge line
consists of highly accurate gauges
designed for use in instrument
shops, plants of all types, and
laboratories throughout industry.
Most models provide sustained
accuracy to 0.25% full scale.
Performance, reliability, and
precision measurement are
coupled with consistency in
meeting the demanding
service needs of numerous
test gauge applications.
OMEGA® test gauges are used
as master reference gauges,
in test stand measurements,
for production inspection,
and for verifying the accuracy
of general service gauges.
The gauge dial has a
stainless steel mirror ring for
pointer reflection, which
prevents parallax error. This
mirror surface reflects the pointer
in any position and allows the
gauge to be read with great
accuracy. The lightweight, frictionadjustable balanced pointer with
knife-edge tip ensures reading
to the smallest subdivision. The
accented dial graduations have
a true width equivalent to 0.25%
tolerance for quick and accurate
gauge checking.

Warning:
all gauge components should be
chosen with an eye to the media
and ambient operating conditions
to which they will be exposed.
Improper application can be
detrimental to the gauge, causing
failure and possible personal injury
and property damage.
