The reason it's necessary for serious baking is that often an oven thermostat doesn't represent the exact oven temperature, and often different spots in the oven can vary 5-10 degrees. This can impact (actually ruin, in some cases) the chance for success, depending on the delicate nature of the project. Baking is really just a big exercise in chemistry: measurement, chemical reactions, catalysts, etc... so the precise heat can be a make-or-break issue.
Usually called a deep frying thermometer, it's a device that measures temperatures in the 200F to 500F range or so by maving it's sensor or probe immersed in very hot fats. It's a requirement for most deep frying.
This type of thermometer is to measure the temperature of hot oil for deep frying food. Typically french fries or other deep fried food is cooked at 350 degrees Fahrenheit on a frying thermometer.
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.
