IMPAC ISR 6 ADVANCED

Stationary, digital ratio pyrometer for non­contact temperature measurement in ranges
between 600 and 3000°C (1112 to 5432°F).

=

The Impac® ISR 6 Advanced pyrometer 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.

IMPAC ISR 6 ADVANCED

OVERVIEW

The ISR 6 Advanced ratio pyrometer uses two adjacent
wavelengths 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

The response time of only 2 ms facilitates the
measurement of fast processes. The ISR 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.

possible up to a certain contamination.

Additionally the pryometer can be switched to 1-color
mode and used like a conventional pyrometer in a
spectral range near 0.9 µm.
