How to choose your indoor thermometer

To help you choose the right indoor thermometer model, it is important to know the essential criteria to consider in order to make the purchase that will perfectly meet your expectations.

#1 - The autonomy

Whether it's an indoor thermometer with a built-in battery, or one with a battery (or batteries) to change. There is no real difference between the two models in terms of efficiency. The inequality can be detected rather at the level of autonomy. A very simple device, which only measures humidity, can last between 6 and 12 months. While for more advanced models, for example, a connected thermometer consumes more energy. It is logical then if its autonomy is less important. For this kind of tool, it is better to turn to a model powered by a mains socket, so that you do not have to change batteries too often.

#2 - The accuracy

What is expected from a technological device is to perceive information of great precision. And normally, an indoor thermometer is only considered to be efficient if it is able to perform accurate and reliable humidity measurements over a wide range. It is therefore best to avoid entry-level models, as their measurements are often inaccurate and could therefore mislead you.

#3 - The display

The good readability of the digital display is really important to read all the information easily. With technology, opting for models that have a very intuitive touch screen is a better choice. Plus its backlighting, this makes navigation more convenient and reading easier.

#4 - The internal memory

This internal memory of the device can collect information in relation to the highest and lowest temperature. This data is easily and quickly accessible to monitor, for example, during the night how low or high the temperature is.

#5 - The dual function

A dual-function model can provide multiple pieces of information about a room. Specifically, a device that can consistently measure temperature and humidity. So, hygrometer and indoor thermometer at the same time.

Use of an indoor thermometer

An indoor thermometer is a tool whose main function is to give the temperature of a room. Having this device is the best way to obtain with precision and accuracy the room temperature of a house. This is really convenient if you have very specific requirements (related to health or your activities, for example). For digital electronic models, this data is displayed on a digital screen, in real time and in a much more precise way. All you have to do is read the information displayed to control the internal temperature of your home so that you can live in the best possible conditions.

This device can be equipped with different types of sensors to analyze the temperature of the air in our homes. This is the case of the thermal conductivity sensor, which uses its ability to conduct heat following changes in humidity to measure the effects of humidity on a dielectric constant. Or the resistive humidity sensor which measures the electrical resistance of a material to know the humidity level.

The different types of indoor thermometers

Are you wondering about the ideal type of thermometer? It is necessary to choose a model that is adapted to your use. Our buying guide will help you learn about the types to consider in order to make the purchase that will perfectly meet your expectations.

Traditional indoor thermometer

Most of this indoor thermometer is in the form of a small glass tube, fixed on a wooden or plastic support and filled with mercury. The model is really classic, so it uses the glass liquid system. This liquid is integrated in the tube which expands on gradual increase of temperature. A graduation helps to read the temperature easily but in an imprecise way and sometimes in shift because the liquid reacts slowly to the temperature change.

In fact, traditional thermometer ranges are not as accurate as modern ones. However, older people still use them, as well as nostalgic people, but on the whole, consumers have very considerably entered the digital age. In addition, this model has not been represented for a long time in the best comparative tests on the market because it has gone out of use by people.

Digital indoor thermometer

Itis often related to the classic mercury thermometer which holds false dial looks. It is also simple to use. Designed on a metal base, the pointer indicates the temperature of the room relatively accurately. Their operation is simple, when the temperature rises, the metal swells and moves the pointer to reach the appropriate value. When it is cold, the opposite process occurs, the metal hardens and the pointer moves down on the dial. It is very affordable, price-wise, but lacks reactivity and precision compared to other models.

At the moment, it'sbetter to opt for the digital models instead, because already you have the choice between a wired or wireless model. Apart from that, this device can either be placed on a table, hung on a wall, or attached to a metal stand via the magnet it is equipped with. And what drives everyone to use the digital models is its technology, such as the presence of a screen allowing for more instinctive handling. The screen is also backlit, and capital information is displayed with large characters, which helps to read the measurements found more easily.

Indoor thermometer or smartphone

Indoor thermometer

The role of this tool is to measure the temperature of a room. At the moment, wireless electronic thermometers are the best known on the market and are highly appreciated for their simplicity and readability. This model is capable of accurate and reliable measurements, plus the built-in technology to connect.

On the other hand, the use of simple mercury-based models, for example, does not ensure much accuracy and reliability. Even though there is a scale that allows you to read the temperature easily, the thermometer is still inaccurate and sometimes shifts because the liquid reacts slowly to the temperature change.

Smartphone

There are many applications to help us better manage our daily lives through smartphones. These phones have the power of a thermometer to give us the precise temperature of the place where we are by the presence of an application that acts like a weather station.

Unfortunately, very few smartphones have a thermometer function. Most touchscreen smartphones do not contain a temperature sensor or instrument to measure the temperature, so it does not allow you to know the exact temperature of the room. This is surprising because normally today's phones are literally armored with sensors.

Verdict

If you want to monitor the temperature of your interiors, having an indoor thermometer will allow you to keep an eye on the evolution of the temperature, with precise data on the ambient air of our homes. It is more practical and easy to use. Apart from that, there are many reasons that require the use of this tool: for a wine or cigar cellar, an incubator, or for the plants in the garden, for example.

A smartphone with a temperature sensor can also provide more reliable temperature readings. And even if your device does not include this type of sensor, nothing is lost. The application will then use the data from the other sensors to get an approximate temperature measurement.

Tips

Install the indoor thermometer properly

A few simple rules must be followed to obtain an accurate, undistorted reading during installation. First, the thermometer should be placed under cover to avoid direct sunlight. Otherwise, it could interfere with the ambient heat and considerably alter the temperature reading. Then, it is better to place it at 1m50 from the ground to have the real temperature of the ambient air. And you should not neglect the good air circulation around the device, but placing it too close to the window is also not a good idea. So, well installed the tool can ensure accurate readings and also avoid damaging the instrument.

Unplug electrical and electronic devices

Infact, computers or televisions even in standby mode also produce heat. It is therefore important to unplug everything. This is beneficial because not only can you lower the energy consumption but also limit the rise of the thermometer.

Adjust the indoor thermometer properly

Toensure reliability, the thermometer must be properly calibrated. For digital models, they do not need this type of calibration. However, if the data displayed seems incorrect, there is a possibility to adjust the device by turning the calibration screw located on the back of the device.

Check the temperature properly

Eventhough other models have an accurate internal memory. And that we tend to move them from time to time from one room to another room, it is necessary to justify and check the information displayed to be reassured.

Fix the tool properly

Alreadyto avoid damaging the instrument you have to fix it well so that you can install it where you want without difficulty. There are some models that are equipped with a metal support via a magnet that allows an exact and very secure fixation of the device.
