2 Introduction
2.1 Appropriate use
The IMPAC ISR 320 pyrometer is a stationary, digital pyrometer for non-contact temperature
measurement on metals, ceramics, graphite, semiconductors etc. in the range between 700 and
1700 °C.
The pyrometer measures in 2-color mode (ratio principle) in which two adjacent wavelengths
are used to calculate the temperature. This technique offers the following advantages when
compared with standard one-color pyrometers:
The temperature measurement is independent of the emissivity of the object in wide
ranges.
The measuring object can be smaller than the spot size.
Measurements are unaffected by dust and other “grey” contaminants in the field of
view or by dirty viewing windows.
The pyrometer can also be switched to 1-color mode and used like a conventional pyrometer.
2.2 Scope of delivery
Pyrometer, PC adjustment, and evaluation software InfraWin, works certificate, and operating
instructions.
Note: A connection cable is not included with the instrument and has to be ordered
separately (see Chapter
8 , Reference numbers).
