Fingertip Pulse Oximeter OLED PO120 – Portable Blood Oxygen & Heart Rate Monitor – No DC
Monitor your vital signs accurately and effortlessly with the Fingertip Pulse Oximeter OLED PO120 (Blood Oxygen SpO2 & Heart Rate Monitor – No DC). Equipped with an advanced optical photodiode sensor and a high-contrast multi-directional dual-color OLED screen, this compact medical monitor delivers fast, non-invasive readings of blood oxygen saturation ($SpO_2$), pulse rate ($PR$), and perfusion index ($PI$) in as little as 8 seconds.
Operating 100% cord-free on standard user-replaceable batteries (No DC adapter, external cables, or mains power tethering required), it slips comfortably into a pocket, sports pouch, or first-aid kit. It provides dependable health tracking for seniors, athletes, respiratory patients, travelers, and wellness-conscious households.
