Nellcor Reusable Adult SPO2 Finger Sensor Oximax DS100A See Description
Nellcor Ds-100a used spo2 sats probe. Will require a good clean as sadly I have no time to do it, some corrosion in the connector but still works 100% (PLEASE DON'T BID IF YOU DON'T AGREE WITH THE ABOVE) price is cheap because of this.
