MOMENT
OF INERTIA INSTRUMENTS - XKR
Series
The XKR Series
will measure parts as small as the balance wheel of a watch
(1 x 10-6
lb-in2
minimum).
Accuracy's
ranging from 0.5% to 0.01% are available.
Construction is
similar to the XR series instruments, except these instruments use air
bearing technology.
