The Contec CMS70A is a tabletop, surface-placed medical monitoring device designed for the non-invasive measurement of blood oxygen saturation (\text{SpO}_2), pulse rate (PR), and perfusion index (PI). Utilizing Photoelectric Oxyhemoglobin Inspection Technology paired with Capacity Pulse Scanning & Recording Technology, this device handles multi-user tracking and offers a hybrid dual-display interface (TFT screen alongside LED segment numerical readouts) for high-visibility monitoring in fixed or transport environments.
