Manufacturers of measuring equipment specialattention is paid to the means to work with the characteristics of air environments. Specialized devices for determining a specific parameter can be found on the market, as well as multifunctional devices that inform the user about a wide range of indicators. Each unit is designed to operate in specific areas and conditions. However, temperature meters can be attributed to universal devices. They are used in the professional sphere, in production, and in the household economy. Those who plan to acquire such a device are faced with the difficult task of choice.
Основным рабочим показателем является sensitivity of the functional element, which determines the range of measured temperatures. So, modern devices are able to record values in the range from -50 to 2200 ° C. Of course, this does not mean that each device is capable of covering the entire range. Extreme values can only be fixed by specialized devices, while conventional temperature meters operate in the range from -20 to 60 ° C. This is explained by the fact that this spectrum is the most common. Going beyond these values is characteristic of production and other special conditions. But in addition to the temperature range, it is important to take into account the error, which can be important in research work, and in planned checks of the operating mode. On average, it is 1-1,5 ° C. For a home appliance, this is a normal indicator, but for professional needs, a more accurate level is required.
В зависимости от условий применения и задач, which are solved with the help of this device, its construction data may vary. Accordingly, the method of use may in each case have its own characteristics. As a rule, on this basis, there are two types of meters - stationary and mobile. In the first case, we are talking about devices that can be installed at critical points, where the state of the air gives an idea of the parameters of the surrounding area. In particular, a temperature meter controller is used in the production, which not only monitors the readings of the air environment, but can also automatically send signals to the communication equipment for the correction of microclimate parameters. As for mobile devices, they are also often used in industry, as well as for research purposes. These are hand-held instruments with which you can measure the temperature of objects.
It has already been noted that instruments may haveprofessional appointment and domestic. Models for specialized tasks have a wider range of operating values, high accuracy and, depending on the application, a set of additional options. For example, medical and construction modifications can be attributed to highly specialized functional devices. Household temperature meters are simpler both in their constructional design and in their performance. Such devices are used to assess weather conditions, in planning various events, etc. Strangely enough, among the models of this type there are quite a few multifunctional devices that allow you to display several readings at once on just one screen. Another thing is that the accuracy of the values in such devices is quite modest.
Usually this category is represented by portablethermohygrometers, which are characterized by high accuracy of the obtained measurements. However, there is a significant drawback in such devices. Since all mobile devices require dynamic measurement modes when moving from one room to another, an important characteristic is the ability to quickly update data. So, the electronic temperature meter requires a long time period for the installation of new readings. But in terms of ergonomics, it is one of the best options for measuring device. An informative display, an intuitive system of settings management and small dimensions are just some of the advantages that digital models have.
Принцип работы таких измерителей обусловлен function of infrared radiation, which forms a kind of pointer from the laser beam. Thus, information is read from the external environment and the temperature is determined. This is not to say that these are the most accurate and perfect devices for performing thermometer tasks, but in some areas they do show the best result. It's all about the possibility of contactless analysis of the environment, which supports this temperature meter. The laser infrared beam is most productive in conditions of operation at high-precision production, where operational assessment of temperature parameters is important. There are also household models of this type, but because of the high cost for home use, laser devices are not advisable to purchase.
Among the most popular options thatmodern devices of this type are endowed, it is possible to single out the standby mode, the ability to save readings, generate statistical data, control ranges of values, etc. The introduction of special operating modes that allow you to optimize power consumption on portable devices is also practiced. Usually such innovations have a battery temperature meter. The digital device also allows you to send data to the base of the computer. But it is important to note here that the electronic “stuffing” itself, in spite of technological development, still does not imply a radical improvement in terms of measurement accuracy. But in terms of ergonomics and convenience, such models are considered the most perfect.
There are devices that are designed only for measurementtemperature, a lot of universal models that can work with almost all the current characteristics of the air environment, and there are thermohygrometers. These are devices that are designed to measure the two most popular climatic parameters - humidity and air temperature. In practice, such devices show good accuracy, despite the combined design. On the one hand, these are temperature meters that can evaluate the thermal conditions in the working room, and on the other hand, they are humidity controllers, without which, for example, the agricultural industry does not do. In this case, it is very important that the two functions are combined in one device, since this allows you to perform a comprehensive survey of the working area with time saving.
Место лидера в сегменте занимает марка ADA и ее TemPro line. Many owners note the high accuracy and physical reliability of the models of this brand, although their cost is quite high. For example, household models with average capabilities can be purchased for 6-7 thousand rubles, and a professional laser temperature meter is estimated at 20-25 thousand. Bosch products also receive good reviews. The owners praise the German devices for easy operation, clear display and low error. The Ryobi company is known for inexpensive, but functional gauges. For example, in just 4-5 thousand, you can purchase a device that will be able to transmit data via the Internet.
Despite the growing demands for measuringdevices, the demand for such products is increasing only in highly specialized sectors. At the household level, such devices still occupy their modest position without special claims to quality and manufacturability. But in production, construction and medicine, the air temperature meter is experiencing all new technical and functional reincarnations. The emergence of electronic and laser devices is only the pinnacle of the modernization process that affects this niche. Along with improving the basic operating parameters, manufacturers also strive to increase the functional support, but without compromising the measurement accuracy.
