To buy a cheap pyrometer you can in any region, but buying cheap devices, most users later realize that this instrument can not solve all problems. Why?
Under the pyrometer (thermometer) means modern technological device that gradually replaces the temperature measurement devices of the previous generation. Sensitive device with a small margin of error, consists of high-quality plastic casing, display for viewing measurements and buttons to change settings (the error sensitivity). This device can conduct high-quality diagnostics and maintenance of different devices suffer from overheating.
If you want to buy a cheap pyrometer, it is necessary to buy the equipment, which meets the technical specification. BALTECH recommends to discuss in detail all the necessary tasks to control the temperature, to make the technical project and send it to the prospective vendor.
Right choice
For the optimal choice of the measuring device need to learn how they work.
The classification of the thermometers is performed by:
- measuring Range;
- Ratio-of-sight;
- design;
- Methods of displaying information (charts, numbers and letters).
measuring Range
On this principle of pyrometers are spectral and temperature.
Low-temperature devices measure negative temperature, high temperature – temperature in excess of 1000 º C. There are combined devices, generating measurement all temperatures, but their price is higher.
The spectral range of the instrument depends on the wavelength of radiation recorded by the pyrometer. With increasing temperature of the object surface, the color begins to shift from the IR-spectral region in the ultraviolet. The measurement accuracy depends on:
- thermometer Type: IR, radiation, colour, brightness;
- Optical characteristics: optical resolution, focal length;
- the emissivity of the material;
- Errors.
design
On execution devices are divided into stationary and portable. Contact pyrometers (thermometers) are used for continuous temperature checking of special materials (for example, melt in the metallurgical industry). In laboratories and in production with their help, record temperatures and regulate the temperature of technological processes.
In places where fixed devices the used practical, portable thermometers BALTECH TL-0215C. They are less precise in measurement, but are characterized by mobility, lightness and compact dimensions. Therefore, outside the laboratories and workshops they have become an indispensable tool, allowing you to quickly determine the location of the overheating condition and insulation. For example, for the diagnosis of hidden electrical components in electric Cabinet we recommend to install an infrared window (IR window) BALTECH TR-55W.
Method information display
Readings can be in the form of diagrams or numbers and letters (text-numeric information displayed on the LCD.
