If you need a good quality pulse oximeter, these are available now on eBay from various sellers at various prices. Mine just came in and I like it.
The current Santamedical “standard” is their newer Generation 2 model. However, that model comes with a higher price tag. This dual color model is still fairly recent. Mine shows a 2020 date. And it costs less than the Generation 2 model. In particular, this dual color oximeter provides you:
- Pulse rate
- Blood oxygen saturation
- Perfusion index
- PPG (photoplethysmograph)
There is, in addition, a visible battery condition indicator.
Cost will vary depending on the eBay seller you choose. But you can find these Santamedical dual color pulse oximeters for south of fifteen bucks with free shipping. Search eBay using the following word string:

In case you’re wondering and because it is not shown,
