XKR Moment of Inertia Small-Payload

Product Details

The XKR moment of inertia measurement instruments are extremely accurate moment of inertia measurement instruments. The XKR offers measurement accuracies better than 0.1% for objects weighing a few grams up to 5 lb (2.3 kg). 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 weighing up to 5 lb can be measured with these instruments.

Measurement Accuracy of 0.1%

Construction is similar to the XR series instruments, except these instruments use air bearing technology.
