Pyrometer CellaCast PA 80

The CellaCast PA 80 was specially designed to measure the temperature of liquid metal at the runner of a blast furnace or cupola furnace. This pyrometer is also ideal for temperature detection where the molten metal is transferred from the melting or holding furnace to the pouring ladle.


  • Temperature range 750 – 2400 °C
  • Maintenance-free, wear-free system for temperature measurement at the melting furnace, holding furnace, cupola furnace and blast furnace
  • ATD function filters out temperatures detected from surfaces free of slag and oxide
  • Dual-wavelength technique provides reliable temperature data despite dust and steam
  • High-resolution optics enable viewing at greater distances
  • Sighting options: through-the-lens sighting, laser spot light or video camera
