Zacurate500BL Fingertip Pulse Oximeter Blood Oxygen Saturation Monitor with Batteries Included (Navy Blue)ClimatePartner certified

It's fast, simple to use. Numbers are easy to read. Handy to have at home or in your vehicle when someone isn't feeling well! Durable and good price.

We got this to check oxygen saturation when wife is having asthma issues. On electronic devices I like to use them awhile before giving a review. So after about 3 years I thought it is time.With the information we get from this easy to use device we can decide on which method is used to alleviate symptoms or if medical advice required. It also will give ongoing heart rate while clipped to the finger which we use to check heart rate and recovery following excercise. This unit uses two AAA batteries and they last a long time. We have been using this 3 years and have yet to need new batteries.

This is the best oximeter I have ever used. It is fast, simple to use, and very accurate. I highly recommend it. I do not often write reviews but this is so good I could not resist.

I bought this Zacurate 500BL to keep tabs on my oxygen levels at home, and it mostly delivers. The device is compact, lightweight, and the LED display is bright and easy to read. It consistently gives results within ~10 seconds—exactly as advertised. The clip fits a variety of finger sizes comfortably, and it comes with batteries and a lanyard—perfect for travel or daily use.Most of the time, pulse and SpO₂ readings match what my clinic records, so I feel confident using it for general wellness monitoring. However, a few people report inconsistent or erroneous readings—especially when fingers are cold or unsteady. A few reviewers even mentioned faults requiring returns, though those appear to be rare.Overall, if you want an affordable, no‑frills pulse oximeter that works well 90‑95% of the time, this one is a solid choice.
