2 Introduction
2.1 Appropriate use
The IMPAC IGA 6/23 is a short wave infrared temperature measuring device with digital signal
processing. It is used for non-contact temperature measurements on metals, ceramics, graphite,
etc. with a temperature range between 50 and 1800 °C.
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).
