I’ll tell you straight - the thermometer outside the window does not show the real air temperature. It shows the air temperature around a building or car. Measuring real surface air temperature is very difficult! There are many factors to consider here.
Thermometer
This should be a professional device, and not a Chinese thermometer from Auchan or Magnit for 50 rubles. Russia has its own production, but there are too many questions about it. In supermarkets you can find an abundance of thermometers from the “First Thermometer Plant”, but in fact there is no plant. There is the First Thermometer Plant LLC, where, according to the Federal Tax Service, 15 people work. The name is made for greater respectability. The choice of products on the site is very rich: external thermometers, for sauna, water, souvenirs, etc. At one time, I bought several standard thermometers, model TB-202 - this is the most common variation. As a result, it turned out that even being next to each other, the error can reach 2-3 degrees. The data was verified based on a digital sensor from a weather station. Its error is 0.1 degrees. It turned out that the thermometers were set to zero incorrectly. A mark is made on the rod with paint, which is sometimes placed a little higher or a little lower, which, of course, affects the measurements. Household thermometers are manufactured according to internal specifications; accordingly, GOST standards do not apply to them.
In addition, there is information that some of the thermometers are collected by prisoners in the Novgorod region. A new production facility has opened in the medical production workshop LIU-3 in Borovichi (Novgorod region) - a site for the assembly of outdoor bimetallic thermometers. The assembly process includes applying scales to the case, after which a screw is inserted into the case, a spring with an arrow indicator is inserted into the case, and the lid is closed; The temperature is set and the finished product is packaged. In less than three months of work, about 75 thousand annual thermometers were collected and handed over to the customer (First Thermometer Plant LLC), reports the press service of the Federal Penitentiary Service for the Novgorod Region. It turns out that no qualifications are required to assemble these thermometers.
If you want to purchase a high-quality thermometer, then look for the necessary equipment in the Unified State Register of Measuring Instruments. This register has the status of a state document certifying that the registered measuring instrument and its manufacturer have passed the necessary formal and significant (in essence) verification procedures, on the basis of which this measuring instrument is included in the list of measuring devices for which official technical standards and rules of metrological verification have been established .
Terrain and heat sources
It is not enough to just buy a thermometer; you also need to understand its location. Often, an outdoor thermometer is affected by many factors that distort its readings. In winter, this is the thermal radiation of the building, open windows, heating systems, etc. All these factors increase temperatures in winter. In summer, these are solar radiation, building radiation and anthropogenic (human) sources of heat or cold. Car sensors also often increase the temperature, especially in cars with a dark body. The temperature measurement is also affected by the terrain. Even a slight lowland can reduce the temperature by several degrees.
To reduce these factors to a minimum, a meteorological booth was invented. It protects thermometers from precipitation, direct sunlight and gusts of wind. It is located at a height of 2 meters above the surface level and is freely blown from all sides. The parameters of the weather booth in the USSR were regulated by GOST 14211-79 “Protective louvered booths for meteorological instruments. General technical conditions". The Soviet legacy still continues to serve faithfully, because thousands of weather stations were developed according to this standard.
As a rule, booths are painted white to reduce the heating of the walls by the sun's rays. Their walls consist of frames and slats that form blinds, which are fixed in the side walls at an angle of 60 degrees to the horizontal, and in the front and rear - at an angle of 40 degrees. This is required to ensure that, while ensuring good ventilation, precipitation does not fall on the equipment.
Weather booths in different countries do not differ much. This is also necessary to standardize measurements. Data from these stations is used to describe the climate of the area, the construction of roads, buildings and other infrastructure.
Conclusion
As you can see, measuring air temperature is very difficult. If you want to know exact numbers, then pay attention to the official reports from the Roshydromet observation network. They are the most objective. They can be found here.

How does a non-contact thermometer work?
Before you choose this type of thermometer, you should know more about how it works. How does a non-contact thermometer work?
Here's what you need to know:
- For its operation, a non-contact electronic thermometer uses advanced optical sensors that measure infrared radiation and, on this basis, are able to estimate the temperature of the test object.
- Infrared radiation is emitted both by the human body and other environmental objects. The thermometer reads the temperature point - the measurement is taken on the forehead - so that the measurement is accurate.
- A non-contact medical thermometer works very quickly - the device is capable of measuring temperature in one or several seconds.
The non-contact thermometer is very accurate in operation, and in addition, most models can be further calibrated to eliminate any interference.

Car thermometers, which are devices that can combine the functions of a voltmeter, weather station and clock, are in particular demand and popularity among buyers.
Functional features and capabilities of car thermometers
The main task is to measure the air temperature outside and inside the vehicle. Most of these devices are equipped with a measuring scale in increments of 0.5 degrees. Taking into account that many modern cars have complex climate control systems, a car thermometer can be an effective addition as a tool for monitoring the operation of the system.
In addition to tracking temperature, car thermometers equipped with remote sensors display the current time and also perform calendar functions. Some modifications of such devices are capable of measuring the voltage of the vehicle's on-board network, air humidity in the cabin, and so on. All indicators are displayed on a modern informative monitor, which, depending on the model, has several backlight options. One of the most useful functions is the ability to detect ice formation on the road.
