Designed for reliable operation in harsh chemical and electrical environments, this fiber optic temperature probe is unaffected by microwave radiation and plasma. It measures temperatures using fluorescent decay, a field-proven technique in hundreds of industrial installations for 25 years. Its patented monolithic single-crystal technology eliminates the need for unreliable mechanical coupling.

  • Each unit includes a controller and one probe
  • Immune to EMI, RF and microwave
  • Operates up to 950 ºC
  • Precise and reliable
  • Inert all-crystalline probe
  • Micro sensing tip

Applications include microwave/RF heating, chemical processing, molten metal measurements, plasma processing, and semiconductor processing.
