Pyrometer Raytek, a series 3i. Characteristics and description
To overcome the limitations of using a contact thermometer at many industrial enterprises, help non-contact infrared thermometers Rautek 3i. For measurements in the environment of hot objects thermometers 3i have a built-Compensated energy reflected or emitted by the background around the object of measurement. Compensation reflected background radiation is needed to accurately measure in particular in those cases where the control zone gets radiation from nearby objects with high temperatures, such as inside the oven.
General-purpose model 3i LT and LR designed to control the temperature in different industrial processes, maintenance and quality control. A wide range of models for optical performance and range of temperature measurement. High optical resolution 105:1 model LRL2SC, a wide range from -30 to 1200 ° C, allow the telescope to measure remote objects from a distance, such as electrical connectors power lines.
Maintenance, paper and pulp industry, events fire safety inspection of contact connections of electrical equipment.
High temperature infrared thermometer, model 3i 1M and 2M are suitable for temperature control in the foundry and steel production, including the operation of heat treatment, tempering and forging.
Due to the high optical resolution 180:1 Model 3i 1M can be used to analyze the temperature distribution in the different zones of furnaces. Allows surface temperature checker and lining smelters to assess the damage to the brickwork.
Recommended for temperatures:
Ferrous metals, Steel, In the process of refining, casting and processing of metals, ceramics, semiconductor manufacturing technology, chemical and petroleum industries.

The first pyrometer was invented by the Dutch physicist Peter van Mussenbrock. These devices could measure the temperature of bodies only visually. Basic calculations were made from data about changing the color and brightness of the hot object. Of course, these indicators were not precise enough. Currently, the functionality of such devices has expanded considerably, it is possible to measure the temperature not only hot objects, but those objects which the figure does not exceed 0 degrees. For example, Optris infrared thermometer measures temperatures ranging from -32 to +900 °C. Improvement of these devices began in the 60-ies of the XIX century. The industry is developing successfully and at the present time. Due to active developments, we have the opportunity to produce industrial thermometers that were equipped with high technical characteristics. With the development of nanotechnology the size of devices is getting smaller, making their use as easy as possible. The first portable model of the pyrometer was developed in 1967, leading the American company Wahl. It was the prototype of the modern infrared devices. The introduction of new technologies and designs allows to improve the functioning of a pyrometer. The main principle was based on the definition of heat energy that was radiated by the object. The widespread uptake of these devices has the opportunity to remotely measure the temperature of both liquid and solids.
