The PI 89 offers outstanding environmental control and enables researchers to do in-situ nanomechanical testing within an SEM with very low to high stresses. The system yields industry-leading force and displacement resolutions and expanded force and displacement ranges, thanks to the integration of a high-performance controller from Bruker, a patented capacitive transducer, and intrinsic displacement control flexure technology.
The modular architecture also enables a wide range of testing techniques for further improvements, including heating and scratch testing.
