Santamedical SM- 165 is a super Finger Pulse Oximeter. It is small, lightweight, and easy to use. Great for people who suffer from Asthma, COPD and other breathing related diseases. I do suffer from medical issues but not so much that I actually NEED one of these, but Im enough of a hypochondriac that I enjoy using it. It is so easy to use, just install batteries place your finger inside and within seconds it will give you a reading. It reads your oxygen and pulse levels very quickly. Whats useful is that with each click of the button you can turn the display so that its easy for you to view. Deeply is very bright and bold numbers make it very easy to read as well in any lighting condition.
It comes with a nice case so that you can take it where ever you may need it. The meter itself is very well built and durable for years of use. If you would like one of your own you can the Santamedical SM-165 Finger Pulse Oximeter at Amazon and purchase with your Prime account for free shipping!
