How to choose a thermal imager and pyrometer. Tips, characteristics, manufacturers Instruments,Plumbing
The thermal imager is a measuring device that determines the occurrence of and increasing the temperature of the surface being studied. It is a chamber, it is also called an infrared chamber with a photosensitive display. Any object having a temperature above - 273Gradus, determines the IR radiation, it is not visible to the naked eye. And the thermal imager helps determine the presence of this object or phenomenon with an increase in temperature. They are displayed on the display of the device as a color field, where a certain temperature corresponds to its color. This device is widely used in industrial production to find faulty networks in various fields in the military industry, in construction, and in recent years, and in medicine.

Properties of thermal imagers
This camera is quite expensive equipment, as it has a complex production technology. Therefore, the acquisition of the thermal imager should be approached with the mind, appreciating all its capabilities. Here are the main parameters to determine the desired thermal imager:
- Determination of the highest temperature on which the thermal imager is calculated. And it directly depends on the area of \u200b\u200bits further use. In the construction industry, to measure the reliability of thermal insulation, the operation of the ventilation systems is enough of the device with a maximum temperature measurement of up to 250 degrees. In industrial production, thermal imagers can be needed with the boundary of temperatures up to 1500 - 2000 degrees.
- Resolution display ability in pixels. Than it is more, the more clearly visible the object
- Optical resolution - at what distance the thermal imager is able to reproduce accurate measurements.
- Automatic determination of the hot-cooled surface area. This function is not presented in all thermal inspers, so its presence increases its cost.
Modern devices have additional functions for more convenient use.
- Replaceable lenses
- Rotary display
- Record voice comments
- Laser beam for clear point instructions, backlight
- Humidity level recognition
- Communication with PC, alarm, etc.
Recommended models of thermal imagers
Consider the most popular models of thermal imagers:
- Testo thermal violars are in great demand and popularity in the market of measuring diagnostic devices. They meet all measuring requirements for these devices. The German manufacturer releases these devices under strict quality control. Testo thermal violars are used both in the construction industry and industrial purposes. One of the most popular model is the Testo 875 thermal imager. This is a budget version of the infrared chamber with a maximum point of 280 degrees. In practice, this thermal imager is used mainly in the construction industry - checking the heating, ventilation, quality of thermal insulation, zones exposed to the growth of mold. As well as to determine the damage to the electrical equipment of small power under high voltage.
- The wide range of FLIR thermal imagers allows diagnosing electromechanical instruments, used in the construction, scientific sectors, allow you to determine the leakage of various gases. A distinctive feature of the Swiss company FLIR is that today it is the only thermal imagers that are capable of determining the infected influenza infected with different virus (avian influenza, swine flu). Such devices are widely used at airports in Russia and abroad, in modern medicine.
- Fluke thermal violars also have a wide range of opportunities for use in various fields. We are manufactured both for industrial use and in the household sphere. Additionally, have a frame-of-frame mode, which allows you to more accurately explore and diagnose the slightest changes. Pretty light, compact and easy to handle.
There are situations where the thermal imager is required for a certain time of use, for example, building a house, or identifying damage in the power grid. And buy so expensive equipment need not. In this case, it can be rented in special offices dealing with equipment rental for various areas.
What is the difference between the pyrometer from the thermal imager
Now, consider a pyrometer. This device, as well as the thermal imager, determines the heat output allocated by the object. But, unlike the thermal imager, the temperature is measured at a certain point, and not on the entire surface under study. There are several types of pyrometers
- infrared pyrometer
- laser pyrometer
- optical pyrometer
An infrared pyrometer allows you to determine the temperature in contactless way. Usually, applied in the conditions of difficult accessibility of the object being studied or due to the possibility of obtaining, for example, burn.
Laser pyrometer has a target designator, when the temperature is determined at a specific point with maximum accuracy.
The optical pyrometer due to the presence of a complex optics system makes it possible to maximize the radiated temperature at long distances. These devices are one of the latest innovations in modern measuring equipment.
Pyrometers, much cheaper than their friend of thermal imager. Therefore, it is quite available in the acquisition for household needs.
Recommended pyrometers
Consider the Testo and Optris Pyrometer most popular for today.
- Testo Pyrometers presented by a wide range of infrared measuring instruments. Many of them have a small size, easy to use. It is also possible to measure from different distances with precise guidance with a laser target designator.
- Optris pyrometers are also represented by many different models. A distinctive feature is the possibility of the smallest objects with a diameter of up to 13mm at a distance of up to 140cm
The examined diagnostic devices help identify the slightest changes in the work of any systems in any industries in the early stages and correct them, most often, without destroying the entire disturbed area. And this will significantly save your means and strength.
