Air temperature meters: overview, types, characteristics and reviews. Temperature gauges laser

Manufacturers of measuring equipment pay special attention to facilities for working with the characteristics of air environments. In 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 also used in the professional sphere, in industries, and in households. Before those who plan to acquire such a device, it is not an easy task to choose.

Main characteristics of meters

The main operating indicator is the sensitivity of the functional element, which determines the range of measured temperatures. Thus, modern instruments 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. The extreme values can be fixed only to specialized instruments, 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 typical for 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 and in routine inspections 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 still required.

Classification by operating mode

Depending on the application conditions and tasks that are solved with the help of this device, its design data may differ. Accordingly, and the method of use can in each case have its own characteristics. As a rule, two types of meters - stationary and mobile - are singled out for this feature. In the first case we are talking about devices that can be installed in critical points, where the air condition gives an idea of the parameters of the surrounding zone. In particular, the plants use a temperature measuring instrument, which not only tracks the air readings, but also can automatically send signals to the communication equipment for correcting the microclimate parameters. As for mobile devices, they are also often used in production, as well as for research purposes. These are handheld devices, with which you can measure the temperature of objects.

Classification according to purpose

It has already been noted that devices can have a professional purpose and a household purpose. 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, to highly specialized functional devices, medical and construction modifications can be included. Household temperature meters are simpler in their design and performance. Such devices are used for estimating weather conditions, planning various events, etc. Strangely enough, among the models of this type, there are many multifunction devices that allow one to display several indications at once on one screen. Another thing is that the accuracy of values in such devices is rather modest.

Digital Measuring Instruments

Usually this category is represented by portable thermohygrometers, which are characterized by high accuracy of the measurements obtained. However, there is a significant drawback in 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 the data. So, the electronic temperature meter requires a long time interval for setting new indications. But in terms of ergonomics is one of the best options for the measuring device. An informative display, an intuitive configuration management system and small dimensions are just some of the advantages that digital models have.

Features of laser models

The principle of operation of such meters is due to the function of infrared radiation, which forms a kind of a pointer from a laser beam. Thus, the information is read from the external environment and the temperature regime is determined. It can not be said 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 non-contact analysis of the environment, which is supported by this temperature meter. The laser infrared beam is most productive in conditions of operation in high-precision industries, where an operative evaluation 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 worth acquiring.

Additional Functionality

Among the most popular options, which are given to modern instruments of this type, it is possible to distinguish standby mode, the possibility of storing indications, the formation of statistical data, the management of ranges of values, etc. It is also practiced to introduce special operating modes that allow optimizing the energy consumption of portable devices. Usually such innovations have a battery temperature meter. The digital device also allows you to send data to the computer's database. But it is important to note here that the electronic filling in itself, in spite of 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 perfect.

Temperature and humidity meter

There are devices designed only for temperature measurement, many universal models that can work with virtually 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 quite good accuracy, despite the combined design. On the one hand, these are temperature meters that can evaluate the thermal regime in the working room, and on the other hand, they are humidity controllers, without which, for example, the agricultural industry can not do. In this case, it is very important to combine the two functions in one device, since this allows you to perform a comprehensive survey of the work area with time savings.

Reviews of manufacturers

The ADA brand and its TemPro line occupy the leading position in the segment. 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 moderate capacities can be purchased for 6-7 thousand rubles, and a professional laser temperature meter is estimated at 20-25 thousand. Bosch products receive good reviews. Owners praise the German instruments for easy control, clear indication and low error. The company Ryobi is known for inexpensive, but functional meters. For example, for only 4-5 thousand, you can purchase a device that will be able to transfer data over the Internet.

Conclusion

Despite the growing demands on 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 any particular 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. Manufacturers, along with improving the basic operating parameters, also seek to improve the functional support, but without degrading the accuracy of the measurements.
