CMS50S Wrist Pulse Oximeter | Wearable SpO2 Monitor with Data Storage & Rechargeable Battery #

Wrist-worn pulse oximeter with SpO2 and pulse rate monitoring, data storage, rechargeable battery, and automatic standby. Ideal for sleep studies, home use, and clinical monitoring.

The CONTEC CMS50S Wrist Pulse Oximeter is a wearable, non-invasive device designed for continuous and accurate measurement of blood oxygen saturation (SpO₂) and pulse rate (PR). Adopting Photoelectric Oxyhemoglobin Inspection Technology combined with Capacity Pulse Scanning & Recording Technology, this innovative wrist-worn oximeter delivers reliable results through the fingertip—making it ideal for both spot-checking and long-term monitoring.

Unlike traditional fingertip oximeters, the CMS50S features a wrist-worn design with a separate finger probe, allowing for comfortable, extended wear during sleep, daily activities, or clinical observation. With built-in data storage, rechargeable battery, and automatic standby functionality, this device offers professional-grade monitoring capabilities in a convenient, portable package.

Ideal for sleep studies, home healthcare, hospitals, oxygen bars, community healthcare, and sports physical care. Can be used before or after physical activity—not recommended for use during exercise.
