A measurement device is provided for measuring a vessel pulse signal of a specific position attached by a mark. The measurement device includes a sensor, a plurality of conductive dots, a determination unit, and a measurement unit. The conductive dots are located around the sensor. The determination unit determines whether the plural conductive dots are connected to each other through the mark to generate a determination signal to indicate whether the sensor has been disposed in the specific position.一種量測裝置,用以量測待測部位的特定位置的血管脈波信號。標記器附著於特定位置。此量測裝置包括感測器、複數導電點、以及判斷單元。該些導電點配置在感測器的周遭。判斷單元判斷該些導電點是否透過標記器而彼此連接在一起,以產生判斷信號來指示感測器是否放置在特定位置。1‧‧‧量測裝置11‧‧‧顯示器13‧‧‧感測器14A...14D‧‧‧導電點40‧‧‧判斷單元41‧‧‧量測單元S13‧‧‧血管脈波信號S40‧‧‧判斷信號
