Description

CONTEC CMS50D Fingertip Pulse Oximeter is a compact, non-invasive monitoring device designed to provide quick spot-check measurements of blood oxygen saturation (SpO₂) and pulse rate. Its fingertip design makes it simple to operate—just place a finger inside the sensor and the measured values are displayed on the screen. The manufacturer describes the CMS50D as small, lightweight, portable, and suitable for applications including home healthcare, hospitals, community healthcare, and sports-related physical care.

The device displays SpO₂, pulse rate, pulse intensity/bar graph, and pulse waveform, providing users with more information than a basic numerical reading alone. Depending on the version, the display mode and screen brightness can also be adjusted. The CMS50D is powered by two AAA alkaline batteries, helping make it convenient for portable and everyday use.
