Stationary, digital ratio pyrometer with possible combination of 1-color and 2-color measurement for non-contact temperature measurements in ranges between 100 and 2000 °C
The IGAR 6 Advanced pyrometer is a digital, compact and fast pyrometer which - depending on the individual requirements - can be operated in different modes.
Besides the 1-color mode (100 ... 2000 °C) a 2-color mode (250 ... 2000 °C) or a special Smart mode can be selected. In Smart mode, the measurements in the range between 100 ... 250 °C will be taken in 1-color mode whereas in the range between 280 ... 2000 °C the measurements will be based on the 2-color method (ratio method). In the range from 250 to 280 °C, a continuous transition from 1-color to 2-color measurement automatically takes place.
In 2-color mode (ratio method) 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.
When the instrument is operated in 2-color or Smart mode, InfraWin provides the option to automatically determine the emissivity. By pushing the button “Emi=xxx% Accept”, this emissivity is set and used for all measurements in 1-color mode or in Smart mode below 280 °C.
The response time of only 2 ms facilitates the measurement of fast processes. The IGAR 6 is equipped with a built-in “dirty window” warning.
The pyrometer can be connected to a PC through an RS485 to USB connection, enabling parameter adjustments to be made using the InfraWin software. This can be used for temperature indication, data logging and further analyzing of complete temperature processes.
