A brief look back at the history of the thermometer
The thermometer is an instrument for measuring temperature that was born towards the end of the 16and century. The first thermometer invented was Galileo’s thermoscope in 1597. The operation of this measuring instrument is based on the expansion of matter and Archimedes’ thrust. The thermoscope tube contains several floating balls on which a temperature value is noted. If this first model of thermometer has a measurement accuracy of 0.5°C, it cannot however measure temperatures that are too high or too low.
Subsequently, the first real thermometer was invented in 1654 in Florence by the Grand Duke of Tuscany. It is an alcohol instrument with 50 graduations. Then in 1702, a Danish astronomer named Ole Roemer also invented another alcohol thermometer that marked boiling water at 60°C.
It was in 1717 that Daniel Gabriel Fahrenheit, the famous German physicist, invented modern mercury thermometers. It is the latter who invented the temperature scale bearing his name. Then, in 1730, René-Antoine Ferchault de Réaumur designed an ethanol thermometer, also known as a wine spirit thermometer.
The famous Swedish physicist Anders Celsius meanwhile developed a mercury thermometer which marks the boiling point of water at 0° and its freezing point at 100°, in other words, in the opposite direction to the thermometers currently used. . After his death, Carl von Linné then proposed to reverse these temperature scales. The degree Celsius was adopted in 1948 after the 9and international conference on weights and measures.
As for the digital thermometer, it made its appearance during the 20and century through the various advances in technology and science.
What is the use of the digital thermometer?
The indoor digital thermometer provides accurate temperature readings inside the house. It can for example help to control the temperature of the pantry or a warehouse so that it does not exceed a certain limit or even allow to know the temperature in the baby’s room. You should know that an inadequate indoor temperature can also cause health problems. On the other hand, there is also the outdoor digital thermometer which has been designed to withstand harsh conditions, such as cold, heat, wind, rain or snow.
The advantage with the digital thermometer is that it displays temperatures as a numerical value, usually on an LCD screen, which makes it easier to read the data. Moreover, some models can transmit or store information for later use, for example.
Here is a special selection of some of the best digital thermometer models:
Our choice: the versatile digital thermometer
We have specially selected for you the gemitto thermometer for its very versatile side. Indeed, this model can display the outside and inside temperature. It has 2 sensors that transmit information to its main monitor. On the other hand, this digital thermometer also has visual and audible alarms that are triggered when the predefined maximum and minimum alarm parameters are exceeded. Alternatively, it can also keep temperature readings for the last 24 hours. The monitor has a wall-mounted and foldable support for better reading of temperatures. This model can work with batteries or USB.
The durable digital thermometer
the ThermoPro digital thermometer is also part of our choice since it is a model that works sustainably. Indeed, this model does not consume a lot of energy, which means that it is able to operate for at least a year and a half with 1 AAA battery. Otherwise, it displays 3 types of emoticons corresponding to different temperature levels. On the other hand, in addition to the temperature level, it also displays the ambient humidity level. This thermometer is able to measure temperatures between -50 and 70°C, as well as humidity between 10 and 99%. It also has a mounting slot on its back and a magnetic stand, so it can be placed almost anywhere. Temperature measurements are updated every 10 seconds.
The precise digital thermometer
We have also chosen for you the Doqaus digital thermometer for interior for its rather precise side. This high-precision model is indeed very popular for its response time of only 5 seconds. And in addition to measuring the ambient temperature, it also displays the ambient humidity level. While its temperature range is between -50 and 70°C, its humidity range is between 10% and 99%. This model also has a button that allows you to select the desired temperature unit, either Celsius or Fahrenheit. Regarding its fixings, it can be mounted on a table and also has a wall and magnetic suspension. On the other hand, the information indicated by this thermometer can be read over a more or less long distance, since it is displayed in large size.
The discrete digital thermometer
the Thlevel digital thermometer interior is also part of our selection since it is a rather discreet model. Indeed, it presents a rather sober appearance and does not attract too much attention. On the other hand, it is more exactly a set of 6 digital thermometers that you can place in each room of your home, whether it is the living room, the bedroom, the cellar, the attic, the pantry, but also in a greenhouse or in a reptile incubator for example. Otherwise, in addition to displaying the temperature, this model also presents the ambient humidity level. Regarding its power supply, this model requires 2 LR44 batteries. If its temperature range is between -50 and 70 ° C, its hygrometry range is between 10 and 99%.
The stylish digital thermometer
While the majority of digital thermometers usually display a rectangular shape, the Otio thermometer meanwhile, it has a round shape, which is why we offer it to you. Through its shape, it will offer a certain decorative touch to your interior. This is an indoor thermometer with a diameter of 77 mm which can be placed on a surface or fixed to the wall. This model also offers 2 units of measurement, namely Celsius and Fahrenheit.
