Braun BNT400 No Touch Forehead Thermometer

The Braun BNT400 No Touch Forehead Thermometer is a dual-function forehead thermometer that lets you take a temperature reading in just a couple of seconds — either without touching the skin at all, or with a gentle touch to the forehead. You aim at the middle of the forehead, between the eyebrows, and read the result. It's a practical option for keeping an eye on a fever at home, whether you're checking a sleeping baby or an older child who's awake and squirmy.

What sets this model apart is Age Precision technology: you select the child's age before taking the reading, and the thermometer adjusts its fever guidance accordingly. The result is shown with colour-coded guidance, which helps take some of the guesswork out of interpreting the number on the screen — useful when you're tired and trying to make sense of a reading at 2am.

Two ways to measure

The no touch mode takes a reading from up to 2.5 centimetres away from the forehead, so you can check a sleeping child without disturbing them or making a sound. The touch mode lets you measure quickly with no need to swipe across the forehead — handy for self-measurement or when a baby is awake and won't hold still. A built-in food and liquid mode is also included for checking the temperature of items other than the body.

How it Works

• Age Precision technology: You choose the child's age before measuring, and the thermometer tailors its fever guidance to that age group, since what counts as a fever can differ with age.
• Colour-coded guidance: The reading is displayed with a colour cue to help you interpret the result more easily, alongside the number itself.
• Positioning guidance system: The thermometer helps guide you to the right spot on the forehead, which supports more consistent placement between readings.
• No touch and touch operation: No touch reads from up to 2.5 cm away for minimal disturbance; touch measures with a simple hold rather than a swipe.

Designed for night-time use

A silent mode lets you take a reading without beeps waking a sleeping child, and a backlit display makes the result readable in a dark room — both genuinely useful when you're checking on a little one overnight. The thermometer arrives ready to use with a protective cap and batteries included, so there's nothing extra to buy before your first reading.

Best For

The Braun BNT400 No Touch Forehead Thermometer is a great option for parents who:

• Want to check a sleeping baby's temperature without touching or disturbing them
• Prefer age-adjusted fever guidance and a colour-coded result that's easy to read at a glance
• Would like the flexibility of both no touch and touch measurement in one device

It may not be the best fit if you:

• Need a thermometer validated for a specific site such as the ear, armpit or rectum

Disclaimer

A thermometer estimates temperature to help you recognise and track a fever — it does not diagnose the cause or severity of an illness. Always follow the device's own instructions for measurement site and technique, repeat an unexpected reading correctly, and read the result alongside your child's age and overall condition. Very young infants and any child who seems seriously unwell should be assessed by a healthcare professional, regardless of a reassuring number.
