Choisir son thermomètre
Considered one of the greatest inventions of the Enlightenment, the thermometer is above all a device for measuring temperature. It serves you daily at home to take your body temperature, but it also assists the great starred chefs in the kitchen, the greatest scientists since the dawn of time or even food factories to meet certain standards. To choose your thermometer, the experts at Thermomè quickly explain to you what thermometers are used for, the different types of thermometer that exist and thus help you to understand how to choose the right thermometer adapted to your needs.

What are thermometers used for? 💡

The thermometer is a temperature-taking device that is used to measure and display the exact temperature value, or a temperature gradient (the degree of heat or cold of an object, in celsius or fahrenheit for that matter) . So far, so good. When we talk about thermometer, we tend to think of that little device that we all have in our bathroom and that take the temperature of the body when we suspect the fever to point the tip of its nose. As you can imagine, if the temperature measurement specialists of offer them complete guide to choosing your thermometer, is that they hide many other functions.

Indeed, the applications of thermometers are multiple; they can have a scientific vocation and be used in meteorology to measure the temperature of the air or that of the morning dew, in medicine naturally and are used to measure body temperature, also in cooking, food thermometers allow pastry chefs and other confectioners to perfectly measure and control their cooking, or even in the industrial processes, where thermometers are used to synthesize chemicals for example. And if these professional thermometers are dedicated to serving science or haute cuisine, they also each have their own domestic version.

Your refrigerator and your freezer space are most certainly equipped with a thermometer, you may have installed a hygrometer thermometer to know if your winter garden is dry, if you have indoor fish, it is likely that you had a digital thermometer to regulate the temperature of the water, etc.

You will agree that with all the usefulness that the special thermometers and professionals, these small everyday objects, we are really talking about a revolutionary invention 😎.

Choose according to the type of thermometer 🌡️

There are many types of thermometers, they are defined according to the characteristics below:

  • L'application (medical, industrial, food, etc.).
  • The type of measurement (temperature only, temperature and humidity, temperature and pH, etc...).
  • The type of sensor (Pt100, NTC, Thermocouple, etc...).
  • The type of display (Digital/Electronic or mechanical).

Some examples below.

medical thermometer

And medical thermometer measures body temperature and possibly makes it possible to make a diagnosis of fever in an adult patient, a child or an infant. Digital thermometer could not be more classic than you find in pharmacies, thermometer without frontal contact in companies since the beginning of the health crisis, ear thermometer more and more common, or infrared thermometer for their ease of use especially with babies or in school infirmaries… There are as many medical thermometers as there are ways to use them.

Some high precision thermometers are specially designed to monitor and control storage and transport temperatures of perishable items such as vaccines or medicines.

hygrometer thermometer

And hygrometer captures humidity. It monitors both temperature and humidity in offices or factories to ensure optimal working conditions. It is equally useful in rooms of the house or other interior spaces to ensure good living conditions. Some hygrometers offer outdoor probes with a temperature alert alarm. This particularly practical function alerts you via an audible signal in the event of a risk of frost, if you are, for example, a professional horticulturist or if you have a domestic vegetable garden.


The thermocouple is a sensor which measures the ambient temperature of a room or surface, for example. This fast-response air or gas probe is equally ideal for measuring the air temperature in refrigerated cabinets, refrigerators, freezers or even storage areas. Its fast response time and large measurement range gives it a wide range of applications. If you cannot find the thermocouple suitable for your use, you can choose a custom thermocouple manufactured by GUILCOR.

Electronic and digital thermometer

The electronic and digital thermometers are equipped withan LCD screen, d’a memory function to follow the temperature readings and their evolutions and often Bluetooth. Very practical with their screen, they are very often used as an ambient thermometer at home for domestic use. Directly displayed in refrigerators or equipped with a possible probe (retractable or not) for food penetration, high-precision digital thermometers are the best friends of cooks to help comply with current legislation in terms of food hygiene, in particular. 

Electronic thermometers are not necessarily digital and vice versa, but the two often go hand in hand.
