Software “Infrasoft”:
AST “Infrasoft “ software is under standard scope of supply.It offers possibilities of connecting three pyrometers simultaneously for parameter setting, view real time graph, offline graph and to evaluate measuring data. Communication between the pyrometer and the software is implemented via a cable connected between the pyrometer and the PC serial port. It comes with record feature, spot size calculator and parameter settings features.
Some of the parameters adjustable via software are
  • Emissivity, Response Time,
  • Clear Time(Peak Picker),
  • Analog Output,
  • Sub Range,
  • Unit Of Temperature(°C/°F) ,
  • Communication mode(Comm.mode).
