CMS50D4 Fingertip Pulse Oximeter | Portable SpO2 Monitor with Adjustable Display #

Fingertip pulse oximeter with SpO2 and pulse rate monitoring, pulse waveform display, adjustable brightness & display mode, and auto standby. Portable oxygen monitor for home, sports, and clinical use.

The CONTEC CMS50D4 Fingertip Pulse Oximeter is a portable, non-invasive device designed for fast and accurate measurement of blood oxygen saturation (SpO₂) and pulse rate (PR). Adopting Photoelectric Oxyhemoglobin Inspection Technology integrated with Capacity Pulse Scanning & Recording Technology, this compact oximeter delivers reliable results through the fingertip in seconds.

Featuring a clear display with SpO₂ value, pulse rate value, bar graph, and pulse waveform, the CMS50D4 provides comprehensive, easy-to-read measurements at a glance. With adjustable display mode and screen brightness, automatic standby function, and low-battery indication, this device is designed for user convenience and energy efficiency.

Ideal for home healthcare, hospitals, oxygen bars, community health services, and sports physical care (can be used before or after exercise, but not recommended during exercise).
