Contec CMS50D Fingertip Pulse Oximeter

A pulse oximeter is a small, non-invasive clip-on device that measures oxygen saturation (SpO2) in the blood and pulse rate. It is commonly used to monitor respiratory conditions like COPD, asthma, or COVID-19, or during physical activity. It helps detect low oxygen levels early, prompting timely medical attention. The device displays results instantly on a digital screen and is portable for home or travel use.
