The  thermohygrometer is that instrument that is frequently used in architecture in order to estimate and measure the level of humidity and temperature in the environment.


What is a thermohygrometer?

The thermohygrometer is an instrument, preferably used in the architectural area, for estimating the humidity and temperature of an environment. There is a wide variety of thermo – hygrometers , which can be easily found on the market . It is a tool that allows us to weigh these factors within a home or structure, in order to calculate the possible quality of life that it offers.

Quality of life is the goal of many companies , institutions and states . It is something that can already be differentiated from the productions of past centuries, whose quality was much more than questionable. The search for quality of service is something that can be seen in the pharmacy or in architecture , both territories very sensitive to various factors that can compromise this objective.


The environment and its conditions are one of those factors.

It is not uncommon that when a person is embarking on the idea of ​​buying a home, one of the primary things to keep in mind is the environment. Is it hot or cold? Is it wet or dry? These are questions that may seem trivial at first , but when we look at things a little further, we realize why they become factors that affect the cost of housing in one way or another.

But, how to know if the house has such or such levels of temperature or humidity? We can say that, for this, instruments such as the thermohygrometer were invented .

This is an instrument specially designed to estimate the levels of temperature and relative humidity in a given environment . It is used preferably in constructions, but also in other situations where temperature and humidity are a constant that somehow reduces the quality of a product or service. They can be electronic or analog, each of these instruments with its own advantages and disadvantages.

Let’s see, now, some of the characteristics of this instrument.

Thermohygrometer characteristics

  • It is an instrument whose application can be found, for example, in the area of ​​architecture.
  • It is an instrument that measures variable levels of temperature and humidity in the environment.
  • It uses, in some cases, the measurement of changes in electrical resistance to estimate the aforementioned variables.
  • It can be a digital or analog type instrument .
  • The Hygrometers Digital can, besides, owning to his credit other functions.


It can be said that the first models of the thermohygrometer were born from the hand of Leonardo Da Vinci , in times of the Renaissance. As such, and since then, this instrument was very rudimentary and had too basic functions . It was, little by little, evolving and incorporating other more sophisticated functions and properties. The normal thing was that this instrument allowed the measurement of humidity levels by evaluating the reaction of an object to it. For example, Horace-Benedict de Saussure used a strand of human hair, as this was especially sensitive to changes in temporary humidity .

What is a thermohygrometer for

Some of the uses that can be given to a thermohygrometer are:

  • Humidity and temperature control of a greenhouse . As some plants are extremely sensitive to these factors, farmers must be extremely careful with their levels. Some plants support and live a certain system better than others.
  • Management of the environmental factors of a pharmacy . Some medications can suffer damage due to humidity and temperature levels , damaging them and advancing their expiration date.
  • Quality control of goods. For example, in architecture. In a construction, certain levels of humidity and temperature put the materials from which some work is made at risk .


Among the existing types of thermohygrometer, we have:

  • Indoor Thermohygrometer.
  • Outdoor Thermohygrometer.
  • Gavimetric Thermohygrometer.
  • Capacitive Thermohygrometer.
  • Resistive Thermohygrometer.
  • Thermal Thermohygrometer.

Parts of a thermohygrometer

Depending on the type of instrument we use, the thermohygrometer has the following component parts:

  • LSD screen.
  • Alarm device.
  • Clock device.
  • Temperature measuring device (Degrees Fahrenheit or Degrees Celsius).
  • Moisture measuring device (in percentage).

How does it work

The thermohygrometer measures the variations in temperature and humidity, starting from the variations that these factors generate in the electrical system . This will detect said variations, and will make the respective translations or transformations in order to give a reading of it.

How to use

Its use, although simple, can be a bit complicated if you do not understand the meaning of the measures it indicates. This is because this instrument measures , for example, different aspects of humidity. This is: absolute, specific and relative humidity. Taking these into account, the thermohygrometer can be used for the purposes that the person who uses it has in mind.


We must emphasize that this instrument greatly facilitates the search for quality that some people have. Whether in medicines, services, or goods, the measurement of humidity and temperature allows predicting their deterioration or conservation.
