Stationary, digital ratio pyrometer for non-contact temperature measurement in ranges between 600 and 3000 °C. The ISR 6 Advanced is a digital, compact and fast 2-color pyrometer for non-contact temperature measurement. The pyrometer measures in the 2-color method (ratio method) in which two adjacent wavelengths are used for the temperature determination.This technique offers the following advantages compared to standard 1-color pyrometers: the temperature measurement is largely independent of the object’s emissivity and in wide ranges unaffected by dust and other contaminants in the field of view.

The measuring object can be smaller than the spot size, measurements through dirty viewing windows are possible up to a certain contamination. Additionally, the pyrometer can be switched to 1-color mode and used like a conventional pyrometer in a spectral range near 0.9 μm. The response time of only 2 ms facilitates the measurement of fast processes.

The ISR 6 can be connected to a PC through an RS485 to USB connection, enabling parameter adjustments made using the InfraWin software. This can be used for temperature indication, data logging and further analyzing of complete temperature processes.

Optional Integrated Line Optics:
Besides the standard optical heads, the ISR 6 Advanced is also available with integrated line optics, which features a special spot in the shape of a line. This provides additional advantages for some applications such as wire production or pouring stream measurements.
