Details

The pyrometers IGA 50-LO plus is adigital, highly accurate pyrometers with fiber optics for non-contact temperature measurement on metals, ceramics, graphite etc. between 250° and 2500 °C.

The instrument is equipped with a fiber and an exchangeable optical head. The fiber and optical head are unaffected by electromagnetical interferences (e.g. induction) and can be used in high ambient temperatures up to 250 °C.

Two different types of optical heads for different measuring distances and very small spot sizes are available. A laser targeting light enables the exact alignment onto the measuring object. The very short response time of below 1 ms facilitates the measurement of fastest heating processes. The pyrometer is equipped with a display which shows in measuring mode the current temperature. Additionally all parameters can be read if they are changed via the integrated keys at the instrument.

Via serial interface and the provided software InfraWin the temperature can be displayed and stored on a PC, parameterizing can also be done.

  • preheating
  • annealing
  • tempering
  • sintering
  • soldering
