The paper addresses the development, qualification and application of modern measurement techniques suitable for pressurised cryogenic windtunnels. Enhanced online model deformation measurements and techniques for boundary layer analysis are described; progress on the development of cryoPSP is reported. The qualification of seeding materials for a performance of PIV is outlined.
