Evanmore Colour Finger Pulse Oximeter Ox Blood Oxygen Heart Pulse Rate Monitor with 4 Display Directions (blue)

Evanmore Colour Finger Pulse Oximeter Ox Blood Oxygen Heart Pulse Rate Monitor with 4 Display Directions (blue)
The oximeter is battery-operated (and batteries are included), accurate, convenient and easy to use allowing you to monitor blood oxygen levels discretely any time, anywhere. Weighing less than 60g with the batteries in, this pocket-sized device really can go anywhere with you and it couldn't be more long-lived and reliable. When the batteries do get low there is a low battery indicator to alert you. The oximeter fits onto an adult finger and measures blood oxygen saturation levels and heart pulse rate which are clearly displayed on a colour OLED screen with 4 display directions for easy reading. Working on the principle that oxygenated blood is a different colour from de-oxygenated blood, the oximeter uses red and infrared light to compare the ratio of oxygenated to de-oxygenated blood giving a highly accurate measure of the oxygen saturation percentage of the blood. Running off 2 x AAA batteries (which are included) with an automatic switch off after 8 seconds inactivity to save power it could not be more long-lived and reliable.
