Acc U Rate® CMS 50D Pulse Oximeter with Silicon Cover, Neck/Wrist cord and Batteries

The Acc U Rate® CMS 50D deluxe pulse oximeter uses the same technology embedded in the CMS 50 DL pulse oximeters (B00COQJ90A) to measure your SpO2 (oxygen saturation) and pulse rate. But most importantly, it features an additional plethysmograph that indicates blood flow.

How does the plethysmograph work?
Each wave corresponds to a heart beat and the wave amplitude corresponds to the amount of blood flowing through the blood vessels. If the wave amplitude is low, this means that your blood perfusion might be too low for a reliable read. You should retake your measurement and make sure that your finger is positioned right under the LED lights. Thus, the plethysmograph allows you to determine confidently if the registered reading is accurate.

In addition, it has an upgraded rotatable multidirectional display, allowing you to view your results in any directions.

Despite the added features, the pulse oximeter remains light and portable, allowing convenient measurement on the go. Suitable for sports enthusiasts like mountain climbers, hikers, skiers, bikers or anyone interested in measuring oxygen saturation and pulse rate. The two included AA batteries allow measurement for up to 30 hours.
