Zusammenfassung:	The utility model discloses a sealing device for non-contact concrete self-constriction measurement. The box body (1) is provided with an opening side (3), and the cover body (2) is matched with the opening side (3) of the box body (1). Wherein the cover body (2) is hermetically connected to the open side (3) of the box body (1); the box body (1) is internally provided with a seat body (15) for placing a test mold of the non-contact concrete shrinkage deformation tester; the seat body (15) is connected to the bottom of the box body (1) in a sliding manner; and the cover body (2) is provided with a non-contact concrete shrinkage deformation tester sensor wire outlet hole I (4). When the non-contact type sealing device for concrete self-constriction measurement is used, absolute sealing can be achieved in the sealing device, exchange between external environment humidity and internal humidity of slurry is avoided, meanwhile, constraint of a thin film on a sensor during thin film sealing can be avoided, it is gu
