Zacurate Premium 500 Sporting/Aviation Fingertip Pulse Oximeter Blood Oxygen Saturation Monitor with silicon cover, batteries and lanyard (Royal Purple)

After the culmination of more than a thousand feedbacks, we are proud to announce the launch of the Zacurate® Premium 500E fingertip pulse oximeter. Both the LED and sensor has been improved dramatically and can measures SpO2 (oxygen saturation) and PR (pulse rate) with extreme precision even at low blood perfusion. Just put your finger into the finger chamber and it will measure your SpO2 and PR within seconds. How does the plethysmograph work? Each wave (see above) 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 is too low for a reliable read. You should retake your measurement and make sure that your finger is positioned right under the LED lights. The 500E also retains the dual color OLED rotatable display, allowing you to view your results in any directions. Suitable for sports enthusiasts and those who are interested in measuring their SpO2 and PR. WARNING! This is not a medical device! This product should be used for sports and aviation only.
