Laboratory Thermometer - The Most Versatile Tool

When studying a compound whether it is solid, gaseous or liquid, the most important thing is to know all its characteristics. From this arises the importance of the creation of different tools for the detection and quantification of each of them. Temperature is one of the most important characteristics that is studied. The instrument in charge of this measurement is the laboratory thermometer which occupies the 24th place. Discover the most versatile tool from our top 30 of the best laboratory materials.

What is a laboratory thermometer?

It is defined as the instrument used to make precise temperature measurements, with a high percentage of accuracy. The tool is commonly made up of an elongated glass tube that has a small bulb at one end. This tool arose from the general need to measure temperature.

Who created the laboratory thermometer?

The creator of the initial model was Galileo Galilei in 1593, an instrument I use to measure the temperature of water. Then in 1612 Santorio placed the numerical scale to the already existing model, which was consider the first clinical thermometer. A little later in 1654 Ferdinand II I apply their own adaptations by closing both ends of the tube. It was but until the year 1714 when Daniel Fahrenheit transformed those models to the Moderna thermometer fully functional. Including Mercury to the model it has also been possible to extend the reading range at high temperatures both as low.

This is why it can be assumed that the creator of the laboratory thermometer is nothing less than Daniel Fahrenheit. Since it was who I manage to perfect the design and make it fully functional. Although there were several modifications, it was the Fahrenheit that made it a full-fledged tool operation. And in fact to this day this design endures.

What is the use of the thermometer?

Although its use is basically only one, that is, the measurement of temperature. Its applications are multiple and we will mention some of them. This tool is practically found in every space, both in a house as a job and even in doctors' offices.

In the home usually when there are children there is a digital thermometer, in addition the refrigerator or refrigeration equipment also he has his own thermometer. A thermometer is also used in the kitchen to cooking of meat and cakes. In some places it is common to own a thermometer environmental to control the overall temperature of the house.

In laboratories, the accessory is used to measure the temperature in products that we are cooling or heating.

How does the laboratory thermometer work?

Some metals, when exposed to heat, dilate, the mercury is particularly sensitive to environmental temperature. This is the component essential of thermometers since due to their dilation we can measure the temperature on a graduated scale.

Basically they work like this: Mercury is liquid at temperatures from – 38 °C to approximately 356 °C. When he submits to a heat shock the mercury contained in the thermometer expands. What it generates that it travels through the tube crossing the numerical scale of the same, in which we can read the temperature. According to the level where the mercury.

Measurements on a thermometer

It has already been clarified that the thermometer is used for perform accurate temperature measurements. However, there are various scales on which this measurement can be made, according to the systems of international measurement. Below we will mention the ones that are used currently:

Degrees Celsius: They are the most popularly known as centigrade and is one of the most popular measurements in thermometers conventional laboratory. These degrees have a scale between 0 °C and 100 °C.

Degrees Kelvin: They are generally used in The United States as it is the measure of temperature pertaining to its system metric.

Fahrenheit: It is a measure of temperature absolute, although it has quite a range of coincidence with degrees Celsius.
Its scale is from 32 °F to 212 °F, thus including 180 lines.

Some thermometers have graduated scales with double measurement in some of these measurement systems. For those who don't own it there are conversion rules between each of the scales.

Types of laboratory thermometers

Of mercury

As the name implies, it is the one that uses mercury to make your measurement.

Digital

Are those that have electrical circuits which they perform a numerical conversion of the received caloric stresses. It is very employed in homes and health services.

Of gas

They are specialized thermometers that are used to calibrate or graduate other thermometers. They are known for their exact characteristics measurements.

The laboratory thermometer has been one of the best tools created, since it has an extensive field of usefulness on many levels. It is for this reason that it has earned the 24th place in the top 30 of the best laboratory materials. Discover many more about this counting in the next articles.
