Zacurate Pro Series 500DL Fingertip Pulse Oximeter Blood Oxygen Saturation Monitor with Silicon Cover, Batteries and Lanyard (Royal Black)

I compared my readings with this Zacurate oxygen saturation device, with the readings at my nurse practioners office just two days ago, and they matched exactly! So easy to use, too! I can see why there are so many 5-star reviews!

Liked the design. I use it to measure my oxygen content.

Unit works consistently and reads without having to adjust the fingers. Readings are very accurate and the ease of use makes it an excellent product. Good Price too.

Highly rated and very affordable.

there were instructions for easy use. Batteries were included.

Relatively comfortable to wear. Battery seems to run down quickly when I use it a lot, but the device has lasted a few years. Good reference measurements for health. If you’re looking for a little bit more coverage, I’d recommend a manual blood pressure cuff. It’s still possible to have high blood pressure with a low resting pulse

Easy to use

Very easy to read

Opened the box and took out everything and it was all there. Inserted the batteries and placed on my finger and presto. Worked like a charm.

Needed this ASAP for husband who was having O2 issues after brain surgery!
