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.

• Athletic Training & Endurance Fitness: Track cardiovascular recovery and pulse response after intense running, cycling, or gym workouts.

• First Aid Kits & Emergency Preparedness: Compact, lightweight addition to family grab-and-go disaster bags, clinic prep stations, or office first aid lockers.

Quick 4-Step Setup & Operation Guide

1. Insert Batteries: Slide open the bottom battery cover and insert 2 fresh AAA batteries, paying close attention to the indicated polarity (+ / -) markings inside the compartment.

2. Insert Finger: Squeeze open the clip and insert an index, middle, or ring finger fully into the silicone chamber until the fingertip touches the built-in stop guide (ensure nail polish or false nails are removed for optimal reading).

3. Power On & Hold Still: Press the front power button once; keep your hand relaxed and motionless while the optical sensors measure your vitals.

4. Read & Auto Off: Note your $SpO_2$ percentage and pulse rate on the OLED display (press the button briefly to flip display orientation); remove your finger, and the unit will shut down automatically after 8 seconds.
