It is recommended to replace a thermometer every 1-2 years to ensure accuracy and reliability. If a thermometer is damaged, it should be replaced immediately.
When using a Fahrenheit thermometer, temperature should be measured to the nearest degree.
You should place the thermometer under your tongue for an accurate oral temperature reading.
An axillary thermometer should be left in place for about 3-5 minutes to ensure an accurate reading.
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 should replace a digital thermometer when it becomes inaccurate. You should also replace it when it is damaged or cracked.
The thermometer should read 100 degrees Celsius when placed in boiling water at standard atmospheric pressure.

For a single thermometer, placement should be in a central location.
You should not leave a meat thermometer in the turkey while it cooks. This is very dangerous and should be avoided.
