Fingertip Pulse Oximeter Blood Oxygen Saturation Monitor SPO2 OLED Pulse Heart Rate Monitor Oximeter

Description A pulse oximeter is a medical device that indirectly measures the oxygen saturation of a patient's blood and changes in blood volume in the skin, producing a photoplethysmograph. This oximeter also displays the heart rate. Make sure to use strong reputable power cells and insert them in the correct position. The finger must be firmly placed over the sensor to get a reading, if it is not placed correctly the oximeter will automatically turn off in a few seconds. Do not open up return-cases in such scenario. Please note that this device has an accuracy range.

It should not be compared to a hospital's £1000 of pounds of equipment. Display - 1.1 Inch - Colour
