Details

The IS 12-Al is a development of the pyrometer IS 12, specially designed for the measurement of aluminum. The robust die-cast housing with protection class IP65 is designed for the use in industrial environments.

The parameters of this digital instrument can be set directly via push buttons on the rear side of the instrument. The built-in digital display indicates the corresponding parameters or the actual temperature reading in measuring mode. The instrument’s parameters can also be adjusted via digital interface with the optional available portable parameterizing device HT 6000 or in combination with the PC software InfraWin. The software additionally allows the display and recording of temperature values graphically and numerically.

The IS 12-Al can be aligned exactly on the measuring object with the optimized thru-lens view finder with spot indication. For exact alignment of the measuring object the instruments are additionally equipped with a targeting light.

Typical Applications:

  • Aluminum extrusion 
  • Rolling 
  • Billet heating and other heating processes
