Used for monitoring pulse and blood oxygen levels this fingertip Pulse Oximeter is lightweight and easy to use running on just two AAA batteries. This device functions by passing wavelengths of light through the body and then recording these readings with a photo-detector, it can then calculate the heart rate as well as saturation of oxygen in the blood, known as SpO2. This non invasive device can be clipped on to a finger, toe or even an earlobe and provides continuous and immediate blood oxygen saturation levels as well as pulse.
