Best Pulse Oximeters of 2026

Last reviewed 19 May 2026 by Best Products UK Editorial Team

Pulse oximeter buying is mostly about which regulatory marking the device carries. CE Class IIa devices have been approved as medical devices for home use; CE Class I devices (or 'CE' alone) often haven't been clinically validated for medical accuracy. NHS Long Covid guidance specifically recommends CE Class IIa pulse oximeters. This ranking weighs medical-certification status above headline features.

How we tested

Best Products UK is a review aggregator, not a test lab. For this guide we read Amazon UK customer reviews focused on reading consistency between attempts and ease of finger-fit; cross-referenced against NHS Long Covid guidance, MHRA medical-device classifications and Patient Safety Learning resources. CE Class IIa marking is treated as the meaningful regulatory threshold — devices without it may still be accurate but lack clinical validation. Skin tone affects pulse oximeter accuracy (studies show readings on darker skin can read higher than actual SpO2); MHRA acknowledges this. This article is informational, not medical advice.

How to choose

CE certification, accuracy and how to use one correctly

Three considerations cover pulse oximeter buying.

1.
CE Class IIa is the clinical-use threshold

CE Class IIa: medical-device certified for home use. CE Class I (or just 'CE'): general-purpose certification, not always clinically validated. UKCA marking (post-Brexit): some devices show this instead. NHS Long Covid guidance specifically recommends CE Class IIa or equivalent. For monitoring under GP guidance — buy Class IIa. For personal awareness only — generic CE is fine but be aware readings may be less accurate.

2.
Skin tone affects pulse oximeter accuracy

MHRA and FDA have both acknowledged that pulse oximeters can read 2-3% higher than actual SpO2 on darker skin tones. This means a reading of 92% might actually be 89-90% — clinically significant. The technical reason: most oximeters were calibrated against lighter-skinned populations. Newer devices (some Masimo, some ViATOM) are calibrated more broadly. If you have darker skin and are monitoring for clinical reasons, discuss this with your GP and consider readings as approximate.

3.
Reading technique matters

Sit still for 1-2 minutes before reading. Warm hands (cold fingers give lower readings — peripheral vasoconstriction). Remove nail polish (especially dark colours) and false nails — they block the infrared light. Take 3 readings and average. Don't measure within 30 minutes of strenuous exercise or smoking. A single odd reading on a usually-healthy person rarely indicates anything; trends over multiple days are more informative than single readings.

For most household awareness use: Braun, ViATOM or generic Amazon device at sub-£15. For clinical monitoring under GP guidance: CE Class IIa device (Braun, ViATOM, AILE UK-approved). Don't use a pulse oximeter to self-diagnose — discuss readings with your GP if they're concerning.

The verdict

Braun Pulse Oximeter 1 wins on brand trust; ViATOM Bluetooth is the data-logging pick.

The Braun Pulse Oximeter 1 takes the top spot because Braun is the UK-recognised medical-products brand pharmacists and GPs see most often. CE Class IIa marking, fingertip SpO2 + pulse rate, designed for at-home COPD and Long Covid monitoring. Slightly more expensive than generic alternatives; the brand and regulatory documentation justify it for clinical-use contexts.

For users tracking SpO2 over time, the ViATOM Bluetooth Pulse Oximeter is the smarter buy. UK-approved (MHRA-registered medical device), Bluetooth connectivity to a phone app for trend tracking, built-in memory for offline storage. Useful for sharing data with your GP via email/print-out.

Below the £15 line, the picture is honest: dozens of similar fingertip pulse oximeters from generic Amazon sellers. They display SpO2 and pulse — most are accurate enough for personal trend-watching but may not have CE Class IIa certification. The 'NHS Long Covid recommends CE Class IIa' guidance matters if your monitoring will inform a clinical decision; for casual personal awareness, generic devices are fine.

Frequently asked

Common questions

What's a normal SpO2 reading?
Healthy resting adults: 95-100%. Above 95% is considered normal. 92-94% may indicate mild hypoxia (low oxygen) — relevant for people with chronic lung conditions. Below 92% in someone who's usually higher is a reason to consult a GP. NHS Long Covid guidance treats 92% as the threshold for clinical concern. Don't self-diagnose from a single reading; trends matter more.
Why does my reading vary between attempts?
Pulse oximeters are sensitive to: cold fingers (vasoconstriction reduces blood flow), nail polish (especially dark colours block the sensor), movement, finger placement (try a different finger), and skin tone (darker skin can read higher than actual). Take 3 readings 1 minute apart and use the average rather than acting on a single number.
Are pulse oximeters accurate on darker skin?
Studies show pulse oximeters can read 2-3% higher than actual SpO2 on darker skin tones. MHRA and FDA acknowledge this. If you have darker skin and are using SpO2 for clinical monitoring, discuss this with your GP. Newer 'multi-wavelength' oximeters (some Masimo professional models) compensate better; consumer-grade devices typically don't.
Should I monitor my SpO2 at home?
Only for specific clinical reasons: Long Covid recovery, chronic lung conditions (COPD), sleep apnea monitoring under GP guidance. Routine SpO2 monitoring in healthy people isn't recommended and can cause unnecessary anxiety from minor readings. Always discuss readings with your GP rather than acting on them yourself.
Pulse oximeter vs smartwatch SpO2?
Dedicated pulse oximeters: medical-grade certification (CE Class IIa), more accurate, designed for spot measurements. Smartwatch SpO2 (Apple Watch, Garmin, Fitbit): less accurate, primarily for trends and wellness — usually not clinically validated. For monitoring under GP guidance, use a CE Class IIa fingertip oximeter; for casual awareness, smartwatch SpO2 is fine.
