The Microlife OXY 300 is a small and compact but high quality oximeter, with which you not only oxygen level in the blood (SpO2), but also immediately see your heart rate (number of beats per minute). The measurement is extremely simple and completely painless. All you have to do is clip the OXY300 to a fingertip and it starts measuring right away.

You can use the Microlife OXY 300 anywhere, at home or on the go. Thanks to the bright OLED screen with 10 adjustable brightness levels and the 6 different display modes, you can easily read your Sp02 and heart rate everywhere under different conditions. You can also easily take the OXY 300 anywhere with the included carrying strap and carrying cord.

A simpler model is the Microlife OXY 200 pulse oximeter. This one has fewer functions but is also cheaper in price.

    For this money you get a good saturation meter. My doctor had me get one. He measured with Microlife, so I did too.
