Overview

The SmartHeart 11-50L is a fingertip pulse oximeter, a small clip-on device that reads blood oxygen saturation and pulse rate rather than a vitamin or supplement. It is listed here in blue and weighs about 0.13 lb.

Despite sitting in a supplements category on this listing, the product itself is a hardware device: a clip that fits over a fingertip to give an oxygen saturation and pulse reading. No seller description or additional spec sheet was supplied, so display type, battery life and accuracy range are not confirmed from the data available.

Who it's for
