Thermal imaging cameras are used wherever temperature is important for the course of the assumed processes. Excessive heating of devices may indicate their malfunction. The implementation of preventive measures in the form of periodic inspections with the use of a thermal imaging camera enables the elimination of failures and downtime in production processes in many industrial plants. Thermal imaging cameras are used, among others, for inspections and tests of electricity distribution systems, electromechanical devices, buildings and roofs, tanks, pipes, valves and tanks. The ATC-02 thermal imaging camera is ideal for controlling ventilation, air-conditioning and heating systems. It is also perfect for imaging the temperature of electrical switchboards, engine components, etc. The infrared image is recorded by a matrix with a resolution of 60x60, the camera has a sensitivity of 0.15 ° C, thanks to which even the smallest temperature differences can be found in the thermal image. It also records the visible image, and thanks to the possibility of overlapping images recorded in the visible and infrared light bands, it makes it much easier to locate points of high or low temperature. The temperature data is stored as a matrix of thousands of points. The obtained data can be analyzed both at the place of measurement and on a PC. The ATC-02 camera is equipped with a memory card reader that saves images in bmp format.
