CMS50EW Fingertip Pulse Oximeter with Alarm/Bluetooth

$89.00 89.00

The CMS50EW Fingertip Pulse Oximeter is a cost-effective medical health device that provides an accurate reading of blood oxygen saturation levels and pulse rate in the body. The oximeter is capable of helping physicians, nurses, patients, athletes, and pilots swiftly obtain SpO2 and pulse rate readings. The wearer’s finger comfortably fits in the device’s padded finger chamber to take a reading. A measurement result is provided in under 30 seconds!

The pulse oximeter features a brightly colored design and small, portable size. The pulse oximeter does not require any external wires or probes when taking measurements. A single button is used for operating the pulse oximeter’s functions. Bluetooth 4.0 connectivity is built-in to the CMS50EW to link to an Android or iOS smart device. A soft carrying case is included for convenient storage.



Powerful technology in the device accurately measures oxygen saturation (SpO2) and pulse rate directly through the finger. An automatic alarm alerts the wearer to the presence of low oxygen levels in the blood. The auditory and visual alarms provide a reliable system for keeping the wearer informed of activity in the body. Additional alarms alert to low voltage and improper placement of the pulse oximeter. A low-profile battery indicator provides a charge status level for the device’s rechargeable battery.

The bright 1.3" OLED screen displays in full color with sharp text and images. The backlit display can be clearly read from up to four different viewing angles. The rechargeable lithium-ion battery replaces the need for traditional batteries that are used in most other pulse oximeters. The battery is charged via the included power adapter or by connecting the unit to a computer. 

The SpO2 and Pulse Rate readings are displayed as a standard value, bar graph, and waveform. All of the display variations are shown on the screen to provide a convenient visual representation of your body’s SpO2 and Pulse Rate levels. The animated images aid in helping  to understand the body’s current health information.

Up to 24 hours worth of measurement data can be easily transferred to a computer using the included software. The software provides an efficient and quickly accessible history of your pulse oximeter’s recorded data. The data can be saved for future reference, or for analysis by a medical professional or physician. 

The CMS50E features many of the same functions that are included on larger and more expensive pulse oximeters. Daily activity tracking, COPD monitoring, sleep studies, home healthcare spot-checking, and medical professional practices are all able to utilize the intelligent health monitoring technology in the CMS50EW. The CMS50EW is a great everyday solution for tracking your body’s health and activity.

CMS50EW Fingertip Pulse Oximeter with Alarm/Bluetooth

Maanual SHoertcommings

The english language syntax was developed on Mars, Assumptions that the user was steeped in oximeter jargon were rife throughout. I have been a user of computers since the mid 1980s and have generally been able to achieve functionality quite promptly. This is not true with the CMS50EW. The user manual scores a D- being nearly totally useless. Note this is applicable to the uploading procedure.

Good product, good deal!

Product price was very fair, compared to other sources for the same item. Received the product on-time, in good condition, and it performs as advertised. Very satisfied, and would recommend to all.
