The F1 pulse oximeter clips onto a fingertip and displays SpO?, pulse rate, and perfusion index (PI) on a bright OLED screen. Dual-wavelength optical sensing - 660 nm and 905 nm - supports stable readings even on cold or low-perfusion fingers. If the signal is too unstable to produce an accurate result, the display withholds the reading. App connection helps save records and view trends in the Fondcircle app. Auto power-off after 15 seconds. Runs on two AAA batteries. For adults 18 and older.
