It is sometimes useful to know the ambient temperature inside a house or even outside, for different reasons. It can, for example, make it possible to ensure thermal comfort or even the health of a person. There is nothing like using a thermometer for this. Here are some essentials to know about the latter, as well as a selection of the best models of digital thermometers available on the market.
A quick look back at the history of the thermometer
The thermometer is a temperature measuring instrument that saw the light of day towards the end of the 16the century. The first thermometer invented was the Galileo thermoscope in 1597. The operation of this measuring instrument is based on the expansion of matter and the Archimedean thrust. The thermoscope tube contains several floating balls on which a temperature value is noted. If this first thermometer model 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 would have been 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 by the name of Ole Roemer also invented another alcohol thermometer that marks water boiling at 60 ° C.
It was in 1717 that Daniel Gabriel Fahrenheit, the famous German physicist, invented modern mercury thermometers. It is also 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 9e international conference of weights and measures.
The digital thermometer made its appearance during the 20e century through various advances in technology and science.
What is the use of the digital thermometer?
The digital indoor thermometer allows you to obtain precise 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 digital outdoor 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 the temperatures as a digital value, usually on an LCD screen, which makes it easier to read the data. Moreover, some models can transmit or store the 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 outdoor and indoor temperature. It has 2 sensors that transmit information to its main monitor. On the other hand, this digital thermometer is also equipped with visual and audible alarms which are triggered when the preset maximum and minimum alarm parameters are exceeded. Otherwise, it can also keep temperature readings from the last 24 hours. The monitor has a wall mount and foldable for a better reading of the temperatures. This model can run on batteries or on a USB socket.
The sustainable digital thermometer
the thermomètre digital ThermoPro is also part of our choice since it is a model that works sustainably. Indeed, this model does not consume much 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 a 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. The 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 fairly 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. If 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 longer or shorter distance, since they are displayed in large size.
The discreet 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 every 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 displays 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 humidity range is between 10 and 99%.
The stylish digital thermometer
While most digital thermometers usually display a rectangular shape, the Otio thermometer as for him presents a round shape, which is why we propose 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 77mm that can be placed on a surface or mounted on the wall. This model also offers 2 units of measurement, namely Celsius and Fahrenheit.
