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
2500 °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 ).
