8801 Servohydraulic Fatigue Testing System Up to 100 kN
The Instron® 8801 is a compact servohydraulic fatigue testing system that meets the challenging demands of various static and
dynamic testing requirements. 8801 systems provide complete testing solutions to satisfy the needs of advanced materials and
component testing, and are ideally suited for fatigue testing and fracture mechanics. The compact design of the 8801 frame
makes it ideal for installation within any laboratory environment, generally without the need for strengthened floors or raised
ceiling heights.

Controller and Software
The Instron 8801 is supplied with a digital 8800 controller that
provides full system control including features such as automatic loop
tuning, amplitude control, specimen protect, 19-bit resolution across
the full range of transducers, and adaptive control technology. It also
allows access to WaveMatrix™ Dynamic Testing Software, Bluehill®
Software for static tests, and other application specific software, such
as the Low Cycle Fatigue or Fracture Mechanics suite.
