The Choicemmed MD300C23 fingertip pulse oximeter non-invasively measures blood oxygen saturation (SpO2) and heart rate. Its OLED screen is backlit for easy-to-read measurements and graphically displays heartbeats and the SpO2 waveform. It automatically shuts off after 8 seconds without a signal.

It runs on 2 AAA batteries, which are included, and features a battery status indicator, pulse bar graph and hanging strap. The package also includes a protective silicone cover, belt case and user instructions in Greek and English.
