Medical grade Pulse Oximeter


Pulse Oximeter with Perfusion Index, 6 levels of Brightness and Display orientation Modes, auto off


Contec Pulse Oximeter CMS50D, 50DA (FDA Approved)

Principle of the CMS50DA Pulse Oximeter is as follows:

Photoelectric Oxyhemoglobin Inspection Technology is adopted in accordance with Capacity Pulse Scanning & Recording Technology, the Pulse Oximeter can be used in measuring the pulse oxygen saturation and pulse rate through finger. The product is suitable for being used in family, hospital, oxygen bar, community healthcare, physical care in sports (It can be used before or after doing sports, and it is not recommended to use the device during the process of having sport), etc.

Check your oxygenation levels as preliminary assessment when you suffer from shortness of breath or experience labored breathing. Also, when one has difficulty or feel like you are grasping for air or any other acute situation whereby one’s breathing or ability to get oxygen from air is affected in any way.

A good choice to have this pulse oximeter as part of first aid or emergency kit.
