Due to its short measuring wavelength the ratio pyrometer optris CTratio 1M is especially suited for measurement of extremely high metal temperatures and the very short response time allows for surveillance of very fast processes.
The ratio pyrometer is largely resistant against dust, steam and dirty observation windows. This allows for an accurate measurement in cases of window soiling of up to 90 percent. The pyrometer additionally measures reliably in cases where the measuring object only covers 5 percent of the measuring point or moves very fast.
Rugged, electrically isolated sensing head and fiber optic cable for ambient temperatures up to 315 °C without cooling.
