  • Infrared interface for transfer of measurement values to a PC
  • Focusable optics with a small measuring fields at large measuring distances


The IGA 315-K portable pyrometer has been specially developed for use in coking plants. It is used for the non-contact temperature measurement of the nozzle bricks and the air stages in coking ovens. Measurements are made from the oven roof after opening the heating flue. For this, the optical path of the measuring instrument is modified in such a way that the nozzle brick can be targeted without difficulty through the small viewing opening and can even be accurately measured at a distance of up to 12 m. For easy sighting, a circular measuring field is marked in the viewfinder, which represents the size of the object to be measured. The correct measuring distance is found by adjusting the focusable optics until the item under test is sharply focused. The temperature indication can be viewed directly in the viewfinder.

Using the one-button operation the instrument can be quickly switched on, or a measurement value can be saved with up to 2,000 measurement values including date and time. Prior to the measurement, a series of measurements can be defined, which for example correlate with the heating flues of an oven. This storage configuration facilitates later evaluation, even if the data is transferred to a PC via the included software. The data can then be both displayed graphically or imported into a spreadsheet program such as Excel.
