2 Introduction

2.1 Appropriate use

The IMPAC pyrometers IS 12, IS 12-S, IGA 12, and IGA 12-S are very robust, digital, and highly

accurate infrared thermometers with temperature ranges between 250 and 3500 °C for non-

contact temperature measurement on metals, ceramics, graphite etc.

For optimal match of the instrument to the application, six different fixed optics and three

different focusable optics with extremely small spot sizes are available. The pyrometer

parameters can be selected via keys and settings are indicated on the built-in LED display. In

measuring mode, the actual temperature is indicated. The pyrometers are equipped with RS232

and RS485 serial interfaces (switchable via the keys). This enables the reading of temperature as

well as reading and adjusting pyrometer parameters using the provided software InfraWin. Two

adjustable limit switches can be used to trigger a switch process, e.g. to recognize hot objects

located in the measuring beam. A thru-lens view finder or additionally a laser targeting light for

exact alignment of the pyrometer is available. The instruments IS 12-S and IGA 12-S are

equipped with an integrated scanner which moves the measuring beam adjustable up and down

up to 4°.

Typical applications: preheating, annealing, tempering, welding, forging, hardening, sintering,

melting, soldering, rolling, brazing, normalizing.

2.2 Scope of delivery

Instrument with selectable optics, PC measurement and evaluation software InfraWin, works

certificate, and operation manual.

Note: The connection cable is not included with the instrument and has to be ordered

separately (see Chapter 10, Reference numbers).
