MOMENT OF INERTIA INSTRUMENTS
XKR SERIES
Model XKR02 moment of inertia
measurement instrument
PRODUCT OVERVIEW
XKR instruments are extremely accurate moment of inertia measurement instruments. Dedicated to small payloads, XKR series will measure parts as small as the balance wheel of a watch
(1 x 10-6 lb-in2 minimum). Payloads up to 40 lb can be measured with these instruments. For more payload capacity please refer to our XR series or GB series.
Accuracies
ranging from 0.01% to 0.1% are available.
Construction is
similar to the XR series instruments, except these instruments use air
bearing technology.
