The photoinjector test facility at DESY, Zeuthen site (PITZ), has been established for developing and optimizing electron sources for linac based Free Electron Lasers (FELs). Characterizations of electron beams with maximum energies of about 25 MeV are carried out at PITZ. In order to study properties of electron beams, several diagnostic systems are applied. One of the important investigations is the study of transverse beam profiles at different beam conditions. Three screen types -YAG powder coated, optical transition radiation (OTR), and CVD-diamond screen- are used as beam profile monitors and are installed in screen stations at different locations along the beam transport line. In addition, wire scanner systems are available in the beamline for the same purpose. In this contribution a comparison of measurement results from all three screen types and the wire scanner used to characterize long pulse trains will be presented and discussed.
