A thermometer must be calibrated before use to avoid false readings.
To overcome errors in a thermometer, you can try calibrating the device according to the manufacturer's instructions. Additionally, ensure the thermometer is clean before each use, and use it in the proper environment to avoid factors that may affect its accuracy, such as extreme temperatures or exposure to direct sunlight. If errors persist, consider replacing the thermometer.
The nurse used a thermometer to take the patient's temperature and monitor for any signs of fever.
use a thermometer.We can feel how hot or cold something is. However, sometimes things are just too hot or cold for us to feel safely. At other times we need to know exactly how hot or cold something is. When we need to measure temperature correctly we need to use an instrument called a thermometer. This measures temperature in degrees Celsius [sometimes called centigrade] or degrees Fahrenheit. There are different types of thermometers for different situations. A medical thermometer, for example, needs to be very accurate. It measures in fractions of degrees. When we are ill, even tiny changes in temperature are important. Some thermometers use a liquid that moves up a very fine glass tube. Most room thermometers, and outdoor thermometers are like this. The liquid is either mercury [ which is poisonous] or coloured alcohol. As liquids get warmer they expand [get bigger], and move up the tube. Water expands too, but not as much as alcohol and mercury. Thermometers that might be used by small children are not made of glass. They use a digital display which lights up the temperature. Inside the displays are chemicals that change colour according to the temperature.
You can use a digital or analog thermometer to measure the temperature of ice, but it's best to use a thermometer that can measure low temperatures accurately. A thermometer that measures from -50°C to 50°C would be suitable for measuring the temperature of ice.
You can use a thermometer to measure room temperature accurately. Place the thermometer in the room for a few minutes to ensure an accurate reading.

The fixed error on a non-digital thermometer is 0.5oC. The percentage error is worked out by dividing 50 by the reading you have taken from the thermometer.
What kind of thermometer you use to measure the body temperature
Use a regular thermometer to test your body (or a child's body) for fever. Use a meat thermometer when cooking meat, and an outdoor thermometer to check the weather outside.
The same way you use a non-science thermometer.

a fever thermometer, is a thermometer that you can use to check your body temperature.
No, it is not safe to use rubbing alcohol in a simple thermometer. Rubbing alcohol is a disinfectant and can affect the accuracy of the thermometer readings. It is recommended to use a thermometer as per the manufacturer's instructions.
The thermometer is broken.Put the thermometer under your tongue.
