Pyrometer CellaCast PA 83CellaCast PA 83 was specially designed to measure the temperature of liquid metal poured from a foundry ladle or discharged from a bottompour ladle.

Features:

• Temperature range: 650 bis 1700 °C
• Maintenance-free, wear-free system measures the pour stream temperature at casting machines
• Optics with rectangular target spot ensures reliable temperature data even when pour stream position varies
• ATD function automatically records a temperature for each cast object
• Dual wavelength technique yields accurate readings despite smoke or dust in the sight path
•  Sighting options: through-the-lens sighting or video camera

• Range of models
