Manufacturers of measuring equipment pay particular attention to means for working with the characteristics of air environments. On the market you can find specialized devices for determining a specific parameter, as well as multifunction devices that inform the user about a wide range of indicators. Each unit is designed for operation in specific areas and conditions. However, temperature meters can be attributed to universal devices. They are used in the professional sphere, in industries, and in the household. Those who plan to acquire such a device are faced with a difficult task of choice.
Key Features
The main working indicator is the sensitivity of the functional element, which determines the range of measured temperatures. So, modern devices are capable of fixing values in the range from -50 to 2200 ° C. Of course, this does not mean that each device can cover this entire range. Extreme values can only be fixed by specialized devices, while conventional temperature meters work 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 industries and other special conditions. But in addition to the temperature range, it is important to take into account the error, which can be of significance both in research work and in scheduled inspections of the operating mode. On average, it is 1-1.5 ° C. For a home appliance, this is a normal indicator, but a more accurate level is still required for professional needs.
Classification by method of operation
Depending on the conditions of use and the tasks that are solved with the help of this device, its structural data may vary. Accordingly, the method of use may in each case have its own characteristics. As a rule, on this basis, two types of meters are distinguished - stationary and mobile. In the first case, we are talking about devices that can be installed at critical points where the air condition gives an idea of the parameters of the surrounding area. In particular, a temperature meter-controller is used in production , which not only monitors air readings, but can also automatically send signals to communication equipment to correct microclimate parameters. As for mobile devices, they are also often used in production, as well as for research purposes. These are hand-held instruments with which you can measure the temperature of objects.
Intended classification
It has already been noted that devices can have a professional purpose and household. Models for specialized tasks are distinguished by a wider range of operating values, high accuracy and, depending on the scope of 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 structural design and in operational qualities. Such devices are used to assess weather conditions, to plan various events, etc. Oddly enough, among the models of this type there are many multifunction devices that allow you to display several readings on one screen at once. Another thing is that the accuracy of the values in such devices is rather modest.
Digital meters
Typically, this category is represented by portable thermohygrometers, which are characterized by high accuracy of the measurements obtained. However, there is a significant drawback of such devices. Since all mobile devices assume dynamic measurement modes when moving from one room to another, an important characteristic is the ability to quickly update data. So, an electronic temperature meter requires a long time period for the installation of new readings. But in terms of ergonomics, this is one of the best options for a measuring device. An informative display, an intuitive settings management system and small size are just some of the advantages that digital models have.
Features of laser models
The principle of operation of such meters is determined by the function of infrared radiation, which forms a kind of pointer from a laser beam. Thus, information is read from the external environment and the temperature regime is determined. This is not to say that these are the most accurate and perfect devices for performing the tasks of a thermometer, but in some areas they really show the best result. The thing is the possibility of non-contact analysis of the environment that this temperature meter supports. The laser infrared beam is most productive in operating conditions in high-precision industries, where an operational assessment of temperature parameters is important. There are also household models of this type, but due to the high cost for home use, laser devices are inappropriate to acquire.
Additional functionality
Among the most popular options that modern devices of this type are endowed with, one can single out standby mode, the ability to save readings, generate statistical data, manage ranges of values, etc. The implementation of special operating modes that allow optimizing the energy consumption on portable devices is also practiced. Typically, such innovations have a battery temperature meter. The digital device also allows you to send data to the computer database. But it is important to note here that the electronic “filling” itself, despite technological development, still does not imply a radical improvement in terms of measurement accuracy. But from the point of view of ergonomics and convenience, such models are considered the most advanced.
Temperature and humidity meter
There are devices designed only for measuring temperature , there are many universal models that can work with almost all relevant 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, these are humidity controllers, without which, for example, the agricultural industry can do. At the same time, it is very important to combine two functions in one device, since this allows you to perform a comprehensive examination of the work area with time savings.
Manufacturer's Reviews
The leader in the segment is ADA and its 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. Owners praise German devices for easy operation, clarity of indication and low error. Ryobi is known for its low-cost yet functional meters. For example, for only 4-5 thousand, you can purchase a device that will be able to transmit data over the Internet.
Conclusion
Despite the growing requirements for measuring instruments, the demand for such products is increasing only in highly specialized sectors. At the household level, such devices still occupy their modest positions without special claims to quality and manufacturability. But in production, construction and medicine, the air temperature meter is experiencing more and more new technical and functional transformations. The advent of electronic and laser devices is just the pinnacle of the modernization process that affects this niche. Along with improving basic operating parameters, manufacturers also strive to increase functional support, but without compromising measurement accuracy.
