CMS-50F Wristband Pulse Oximeter with Software

$89.95 89.95

The CMS-50F Wristband Pulse Oximeter reads SpO2 and pulse rate with a swift measurement reading from the finger. The padded external probe was made to comfortably accommodate a wide variety of finger sizes. The device is suitable for infants, children, and adults. 

The high-contrast OLED screen enables use of the device in dark or low-light conditions. Body activity information updates in real-time on the CMS-50F’s screen.  A variety of data visualizations are used to help the user understand the oximeter’s measurement readings. A standard value, animated bar graph, and animated waveform are clearly displayed on the sharp backlit display.

The FDA approved CMS-50F uses an audio/visual alarm system to alert to improper body placement, high/low activity readings, and accidental detachment of the external probe. The range for limit alerts is adjustable based on the user’s preference. An included clock function and pulse rate tone aid in tracking. 

The innovative design of the CMS-50F includes a rechargeable lithium-ion battery that enables up to 20 hours of working usage time. Traditional batteries found in other pulse oximeters are expensive to replace and are limited by a short battery life. The battery’s current charge level is displayed with an icon on the pulse oximeter’s screen.

The CMS-50F uses an external oximeter probe for taking readings. The wired probe is plugged into the device’s probe input port and securely fits on the user’s finger. The probe is sweat-proof and can be used before or after sport/exercise activity.

Measurement data history can be transferred to a computer for detailed reference, or analysis by a health professional. The included software and data transfer cable enables a quick transfer of the health information that has been recorded with the CMS-50F. The CMS-50F is a great everyday solution for monitoring your body’s health and activity.
