Tested for reading consistency, display clarity, responsiveness, comfort and everyday usability.
Our assessment
Final Verdict
Beurer PO 40 adds a graphical pulse display and perfusion information to the usual oxygen-saturation and pulse-rate figures.
The screen is informative once familiar, and the device remains small enough for easy storage and travel.
The extra screen information can initially feel busier than the simpler layouts above it, particularly for users who only want the two basic readings.

WHY THE RIGHT PULSE OXIMETER MATTERS
A useful pulse oximeter should settle quickly, display results clearly and make correct finger positioning straightforward. Technique, circulation and movement can affect any fingertip reading, so consistency matters more than a single isolated number.
ADVANTAGES OF HIGH-RATED PULSE OXIMETERS
- ✓Fast, repeatable resting spot checks
- ✓Clear SpO₂ and pulse-rate display
- ✓Comfortable finger chamber
- ✓Simple one-button operation
- ✓Readable results in varied lighting
- ✓Compact storage and portability
- ✓Clear low-battery indication
- ✓No unnecessary account setup
- ✓Dependable construction for regular use
THINGS TO CONSIDER WHEN CHOOSING THE BEST PULSE OXIMETER
Reading Consistency
Repeat a reading after resting with a warm, still hand. Look for a device that settles rather than continually jumping between values.
Display Clarity
Oxygen saturation and pulse should be easy to distinguish without interpreting a crowded screen.
Finger Fit
The chamber should hold position securely without excessive pressure or allowing the device to move.
Intended Use
Consumer fingertip oximeters are intended for spot checks. Continuous or clinician-directed monitoring requires an appropriate medical system.
Symptoms Matter
Do not rely on a home oximeter to dismiss concerning symptoms. Seek medical advice when readings or symptoms cause concern.
IMPORTANT SAFETY CONSIDERATIONS
Pulse oximeters can be affected by movement, cold hands, nail products, circulation and positioning. Use the device exactly as instructed and discuss concerning readings or symptoms with a qualified healthcare professional.
