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

Small but handy to carry in pocket to take readings.

Awesome product. Perfectly priced.

I have only been able to get an accurate reading on my little finger. Perhaps because other fingers are a little bit calloused with age? It also seems a little slow at calculating. But not bad for $20. Just dont get too upset if your reading is too low. Try other fingers before calling 911!

Útil, sencillo y de buena calidad; sin embargo, no sirve para pediatria porque demora un poco en hacer la lectura con dedos delgados y pequeños.

Opened the box, put in the batteries, worked like a charm.....the next day I was going for a Dr. Appointment....took my new pulse-ox with me, had the nurse take my o2 reading with her tester, and then used mine, and it was the EXACT same reading.....very pleased with product...

Saved my life

This is my second purchase of this product. The first I used at home the second was a gift to my parents. They use it daily and have no problems. This unit is simple to use and the screen is large and clear.

Works great. Went to DR appt and compared with theirs and same out come

Bought just to have available for potential future illness. Since they’re so cheap these days it seems like a good idea to keep at home next to the thermometer. As far as I can tell it appears accurate. I get the same pulse measurement when I take my pulse manually. I do recommend giving the pulse reading a minute or two after you start the device before you trust it. It does seem to need a moment to read your pulse before it becomes accurate, which I guess makes sense. Can’t speak to the accuracy of the oxygen reading since I don’t have anything to compare it against except to say the reading indicates my blood oxygen is normal and I’m currently not ill.

Very easy to read
