Hey guys, today in this post, we are going to tell you about a thermometer and its working principle. Also, you will come to know about the different varieties of thermometers.
Let us make you recall your childhood days when you must be feeling under the weather at some point in time and running a temperature simultaneously.
You become so grouchy and restlessly loiter around the house with the symptoms of a febrile sickness, feeling unwell and nauseous.
Now, it is time for your parents to check your body temperature before consulting a doctor or any other qualified medical expert.
What is a Thermometer?
Therefore, they shove a pencil-thin instrument in your mouth under your tongue, or in the centre of your armpit. The instrument contains a fluid (mercury, in liquid state) inside it and displays a measuring scale on it.
This very instrument is known as a thermometer, or a glass thermometer, to be precise. After placing the thermometer on the designated place for a minute, the temperature can be easily read up to the level to which mercury has risen, in case of an analogue thermometer.

In case of a digital or electronic thermometer, you are alarmed by a beep sound after a minute and the digits on the screen display the temperature of your body, in degree Celsius.
So you see, measuring the body temperature at your home itself is such a cakewalk, and germane medicaments can also be given at home itself if it seems like a conventional fever.
A thermometer can not only measure the body temperature, but also the temperature of various other elements existing in all the three states of matter such as food, water, air etc.
Many of us have undergone the process of getting the body temperature measured by means of an analogue thermometer, as back in those times we weren’t equipped with the digital ones.
But kids nowadays, who are born with a silver spoon, can get their body temperature checked in a jiffy, by means of a digital thermometer. The common unit of measurement of temperature used in our country India is degree Celsius.
Types of Thermometer
As our medical science and technology took an upsurge with time, scientists started developing thermometers that are digitally advanced and accurate in finding the exact temperature of the body, by putting less effort.

Achieving this goal was possible by inventing thermometers that can easily detect and display the accurate body temperature when the thermometer is palpated on various different parts of the body. Some such thermometers, that were an epitome of innovation and creativity, are described below.
Digital or indoor Thermometers
These are the most generic, common and basic type of thermometers. These thermometers are ubiquitous and can be found in every small or big medical or pharmaceutical store.
Besides being basic and easily available, such thermometers are well known for their accuracy, precision and delivering fast results.
In order to obtain the body temperature reading from this thermometer, you are supposed to place it under the tongue or under the armpit and receive the readings within a minute.
As far as indoor digital thermometers are concerned, they are used to denote the temperature of a particular place, especially a room, a chamber or any covered private space. It possesses a display screen on which the digits are displayed that emanate information about the temperature of that place.

With a wide variation in the models and its types, there are also such types of digital thermometers that can provide information about outside temperature, barometric pressure, humidity etc.
Placing the indoor thermometer at an appropriate position or a place is a crucial step so that it gives an accurate temperature reading. Such thermometers are also known as room thermometers.
Electronic ear Thermometers
Also known as Tympanic thermometers. Scientists developed this type of thermometer to prove the infrared radiation technology fruitful for medical sciences.
Parents with mischievous and frisky kids prefer to use such kinds of thermometers, as their playful children cannot stick to one place for long, and hence using a digital thermometer on them would be completely futile.
The downside of such thermometers is that they are quite expensive, and do not provide accurate reading if there is a superfluity of ear wax inside the ear. Please bear in mind that these thermometers should not be used on newborn babies.
This thermometer also uses infrared technology to detect the temperature in your body. It is being widely used for the screening process (detection of fever or high-temperature) amidst the coronavirus outbreak.
Its sensors are placed in the centre of the forehead, where the temporal artery is located. Then we slide the thermometer slowly across the forehead towards the top of the ear, keeping it in contact with the skin.
The process is stopped when we reach the hairline. The temperature readings are noted. But even these thermometers are not as reliable as the digital ones.
Plastic strip thermometers
These thermometers are by far, the most inefficacious ones present in the market. It is so because they can just detect whether the person is suffering from fever or not.
They fail to dispense precise temperature reading. Hence, these thermometers can only clear your doubts if you are sceptical about the presence of a fever.
Just place a strip on your forehead and wait for a few minutes. Then remove the strip. A coloured number or line appears on the strip which denotes the temperature reading.
This thermometer is the ideal one for young children and babies who are over 3 months of age. It must be used on the babies while they are fast asleep.
This is because it requires the baby to be stationary for a couple of minutes, and hence, using it can be quite a task when the baby is wide awake. It comes with a fever alert glow feature that indicates the presence of fever in the child.
It can deliver the temperature reading in both the units- Fahrenheit and degree Celsius. Also, it contains a protective cover that can be used while travelling.
Last but not the least, it possesses an auto power-off feature which saves the battery from getting drained. In all, the finest instrument available in the market to detect fever in babies, infants and young children.
Digital candy thermometer
This thermometer is used for such purposes that are totally unimaginable and out of the blue. These thermometers are used in kitchen utensils during the process of candy making.
Candy making is a herculean task and the selection of appropriate temperature is an epoch-making step that decides the savour of the final cooked candy.
Measuring the temperature of the ingredients before cooking the candy with regards to the weather is a pivotal step. Due to such applications, the digital candy thermometer is also known as the deep-fry thermometer.
Candy making at home is quite a prevalent practice in the States, and hence, it is easily available at any supermarket store in the U.S.
By far, this kind of thermometer is the one which is quite rapid in action and produces accurate results. It is also used for measuring body temperature and can deliver the results within seconds, anywhere ranging from 8 seconds to 30 seconds. It produces the result in terms of colour codes that help you infer the meaning of the coloured reading.
A green colour depicts that there is no fever, yellow one denotes a slight presence of a fever or a possibility of a fever and the red colour confirms that the person is running a temperature.
This thermometer can either be used orally, rectally or by placing under the arm. This is one thermometer which can prove itself to be the best bang for your buck.
This thermometer is the one which can be considered to be falling under the category of the candy thermometers. But this thermometer is used for a different purpose.
Unlike candy thermometers, this thermometer is used for cooking foods at an appropriate temperature. So the next time you are preparing/heating your food using an oven or using the refrigerator to store/preserve the left-over food or other comestibles, you can always check its temperature to see whether your appliance is functioning correctly or not.
Taylor thermometers have been holding a prominent place under the category of food thermometers and have been serving the purpose for over 150 years now.
One thing that adds feather to the cap is its reliability, brilliant performance and accuracy in delivering temperature readings.
A pool Thermometer is an instrument that helps you to determine the temperature of the water in your swimming pool. Some people have specific needs according to the type of water they prefer to swim in.
Children are really sensitive towards hot water and the elderly have an aversion towards cold water. Hence, maintaining a moderate temperature is very essential so that people of all age groups can relish their swimming experience.
Therefore, this instrument allows you to measure and regulate the temperature of the pool water. With the help of this instrument, you can also keep a check on your pool heater, if it develops a technical snag.
These thermometers come in two variants- Digital or wireless pool thermometer, and analogue thermometer. Digital pool thermometer, despite being expensive, is the most preferred one and dispenses accurate temperature readings. The analogue pool thermometer is cheap but is not as efficient as the digital pool thermometer.
