Abstract: The present invention relates to a measuring equipment for testing an elongation, a bending and a radial compression of a stent. The stent measuring equipment comprises: a test chamber (100); a temperature control chamber (200) accommodating a heating unit (210) and communicating with the test chamber through conduit lines (211, 212); a template (110) including a plurality of guide lines (111) having concentric semicircular shapes formed in a radial direction and a plurality of position holes (112) formed at predetermined intervals in a diametric direction of the guide lines (111); a load cell unit (120) provided above the template (110) including a load cell (121) that detects the load applied to a stent (S); a holder unit (130) for fixing and supporting the stent (S) in the test chamber (100); and a temperature sensor unit (140) for detecting the temperature in the test chamber (100). All tests on elongation, bending and radial compression of the stent can be conducted through a single measuring equipment by replacing only the holder unit for exclusive use, thereby performing efficient tests on the stent.
