MODEL 142D AND 143D FILM/SCREEN CONTACT TEST TOOLS

Film/Screen Contact Test Tools Model 142D AND GAMMEX 143D
Good film-screen contact across the entire area of the screen is needed for quality diagnosis.  Routine testing of all of the cassettes in the department detects areas of poor film-screen contact as part of the QA process before blurred areas  interfere with patient care.  Such testing is often a regulatory requirement.  The Gammex 142D and 143D film-screen contact tools can test cassettes of any size up to 14x17 inches.  The 142D is wire mesh, and the 143D is perforated brass.  Both are enclosed in a protective cover.
