Pyrometer CellaCast PA 80

Features:

• 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
