Depan Pulse oximeter M 130Finger pulse oximeter to measure human blood oxygen saturation and heart rate . Depan The M 130 pulse oximeter enables non invasive, local measurement of hemoglobin oxygen saturation in the arterial part of the bloodstream. An advanced DSP algorithm can reduce the effect of motion artifacts and increase measurement accuracy at low perfusion. The range of hemoglobin saturation measurements is from 35 to 100% and the heart rate from 25 to 250 beats per
