An infrared thermometer can take a temperature quickly without touching the skin. This is particularly useful for babies, sleeping children, older people or when you’re out and about. However, measuring methods, ease of use and extra features vary considerably. A high price or a long list of features doesn’t automatically mean a device is right for you.
A contactless thermometer usually measures temperature at the forehead from a set distance. Even a slight error in positioning, sweat on the skin, a cold room or a hat can affect the result. Models with a distance sensor, positioning aid or clear instructions can help reduce user error, but they don’t replace correct use.
With a forehead thermometer, the measurement area should be clear. After being outside, it’s a good idea to wait a few minutes at room temperature before taking a reading. To monitor changes over time, try to use the same measuring method each time.
A 6-in-1 device sounds versatile. However, if you only want to check body temperature, you may not need to measure liquids, surfaces or room temperature. Conversely, a thermometer for room and object temperatures can be useful if you regularly check bath water, milk or the room temperature.
It’s important to keep the modes clearly separate: an object reading isn’t intended to assess body temperature.
An audible or colour-coded fever alert helps you spot unusual readings more quickly. However, the thresholds vary depending on the model and measuring method. For children and babies, the alert shouldn’t be interpreted on its own. If you’re unsure, the temperature remains high or your child seems unwell, seek medical advice.
An easy-to-read LCD or LED display is helpful at night and for older people. Useful features include silent mode, automatic shut-off and a Celsius display. A memory function can help you monitor readings over time, but shouldn’t lead you to make a medical assessment.
For families with babies, a silent reading is often useful. When choosing a thermometer, also check whether batteries, a storage case and easy-to-understand instructions are included.
Clean the probe or sensor area in accordance with the manufacturer’s instructions. Many devices are made from ABS plastic; some models also specify BPA-free materials. As a rule, an infrared thermometer shouldn’t be fully immersed in water.
For products that use button or AAA batteries, keep the batteries out of children’s reach. Before buying, also check that the device is approved for the intended age range and read the manufacturer’s guidance on medical use.
Why this product suits this profile: According to the product details, it measures forehead, ear and object/room temperatures and is suitable from birth.
The three measuring modes keep things simple, without requiring an extensive 6-in-1 feature set. The memory stores up to 20 readings.
According to the product description: LED display, silent mode, automatic shut-off after 10 seconds and two AAA batteries included.
Why this product suits this profile: This model combines contactless and touch forehead readings with a positioning aid and an age-based display.
According to the product details, PositionCheck helps you align the thermometer correctly using a targeting light, distance sensor and on-screen prompts.
Colour-coded display, Silent mode, and measurement of body, liquid and food temperatures, according to the manufacturer.
Why this product suits this profile: A good choice for households that want to measure room, liquid and surface temperatures as well as forehead and ear temperatures.
The six stated measuring functions are clearly distinguished. This makes it easier to decide before buying whether you’ll actually use the extra modes day to day.
According to the product description: colour change as a visual fever alert, date and time display, and memory function.
Why this product suits this profile: According to the product details, this ear thermometer is suitable for children from birth and adults, and displays a reading in around one second.
The small probe is designed for ear measurements. Correct positioning and adult supervision are still essential when using it.
Audible alert from 37.6 °C according to the product details, memory for up to seven readings, and switchable display in °C or °F.
We’ve put together a complete, regularly updated list of products that meet these strict selection criteria and fully comply with the safety regulations in force in the EU.
A contactless infrared thermometer detects the heat radiation emitted by the forehead or another surface. For useful readings that can be compared, follow the manufacturer’s instructions for distance, measuring point and use. Sweat, draughts and moving between indoor and outdoor temperatures can affect the reading.
Its lifespan depends on the batteries, sensor, cleaning and storage. Keep the device dry, away from direct sunlight and store it according to the instructions. On many models, automatic shut-off helps reduce battery use. Don’t continue using the thermometer if the casing or sensor is damaged, or if the display is unclear.
For battery-powered models, the main ongoing cost is replacement batteries. Devices with a memory function, object mode or illumination may use more power, depending on how often they’re used. Before buying, it’s worth checking the battery type, automatic shut-off and what’s included. For basic home use, a digital stick thermometer with a button cell may be enough.
