Clinically validated according to Braun, but without the pre-warmed tip used on the ThermoScan 7+.
- Suitability by age20% of score7.5

- Ease of use20% of score8.0
One button and a 1-second reading.
- Night-time use10% of score5.5
No night mode, and the fever alert is a series of beeps.
- Fever guidance & memory10% of score6.5
Beeps once for normal, twice for elevated and four times for high, and recalls the last reading.
- Value & running costs10% of score8.0
Often under £20, though it still uses disposable caps.
The full review
The ThermoScan 3 is Braun's entry-level ear thermometer. It takes a reading in a second, has a single button and tells you roughly where you stand with beeps: one for normal, two for elevated and four for high. It recalls the last reading and comes with 21 hygiene caps.
What you lose compared with the ThermoScan 7+ is the clever stuff: no pre-warmed tip, no Age Precision colour coding and no night mode. That last one matters more than it sounds. If you're checking a toddler who has just dropped off, four loud beeps are the opposite of helpful.
It's still a proper ear thermometer from the brand most UK pharmacies stock, and prices swing a lot, so it's worth waiting for a deal. The usual ear-thermometer caveats apply: NICE recommends underarm readings for babies under 4 weeks, and the NHS warns that ear readings can mislead if the probe isn't positioned properly.
