The invention discloses a detection method and a measurement device for measuring the sag resistance value of brazing foil. The detection method comprises the following steps: (1) preparing a materialneeding to be detected into foil to be tested; (2) clamping the foil to be tested in the measurement device; (3) placing the measurement device clamping the foil to be tested in a muffle furnace; (4)sequentially carrying out rapid heating, continuous heat preservation and cooling treatment on the foil to be tested; and (5) taking out the foil to be tested together with the measurement device, and measuring and calculating a sag value. According to the detection method and the measurement device, the sag resistance capability of the brazing foil is directly measured through the special measurement device and a direct heating detection mode, the measurement result is accurate, and the measurement speed is high. 本发明公开了一种用于钎焊箔抗下垂值测量的检测方法及测量装置，包括以下步骤：①、将需检测的材料制成待测试箔片；②、将待测试箔片夹持在测量装置中；③、将夹持有待测试箔片的测量装置放置于马弗炉中；④、对待测试箔片依次
