Key Features

  • Temperature ranges between 550 and 3500 °C
  • Short response times < 1 ms
  • Extremely small spot sizes min 0.1 mm
  • Distance ratio up to 900 : 1
  • Built-in 5 digit LED display
  • Thru-lens view finder, or with additional laser targeting light
  • Test current output
  • 2 fast limit switches Interfaces RS232 / RS485 switchable
  • With fixed or focusable optics


The IS 12, IS 12-S, IGA 12 and IGA 12-S are very robust, digital and highly accurate pyrometers for non-contact temperature measurement on metals, ceramics, graphite etc. For optimal match of the instrument to the application 6 different fixed optics and 3 different focusable optics with extremely small spot sizes are available.

The pyrometer parameters can be selected via keys, the 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 additionally enables the reading of temperature and pyrometer parameters via the provided InfraWin PC-software. If necessary the parameters also can be changed via PC.

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°.
