How we uncover the best pulse oximeters

We test every pulse oximeter we review to ensure it gives accurate results and is easy to use.

It’s impossible to tell how well a pulse oximeter works just by looking at it, so we test every single one against British Standards to make sure they’re up to scratch.

We don’t just uncover the highest-performing products in our reviews, either - we also name and shame any Don’t Buy pulse oximeters that fail our tests.

  • We compare every pulse oximeter reading we take with those taken using medical-grade equipment, to reveal which models are up to the job and which ones fall short.
  • Our tester panel rates each model for comfort and ease of use, to weed out pulse oximeters that clamp too tightly, feel heavy or are tricky to interpret.

How we uncover the best pulse oximeters

We take hundreds of readings for blood oxygen saturation and pulse rate to uncover which pulse oximeters are accurate when you use them at home.

  • We rate each pulse oximeter on the time it takes to generate a stable blood oxygen (SpO2) and pulse rate reading, using a panel of testers with a range of different skin tones.
  • We inspect the supplied instructions and set up the pulse oximeters in our lab to assess which ones are the most clear and straightforward to use.
  • We analyse how easy it is to read the display and operate the controls, so you can be sure you’ll be able to get the information you need quickly.

Pulse oximeter reviews you can trust

We’ve tested pulse oximeters from big-name brands such as Braun, as well as models from smaller, lesser-known retailers. Spending a lot doesn’t guarantee you’ll end up with the best model, and our test results prove that.

Which? is independent - we work for you, the consumer, so you can be sure that our product recommendations are based only on our test results. We’re not influenced by third parties and we don’t accept freebies from retailers or manufacturers. We buy all the products we test, so we can help you to make the right decision the first time around.
