The Sekidenko OR4000T is a multi-channel, non-contact optical fiber temperature pyrometer that measures infrared energy being emitted from an object and converts it into usable temperature data (degrees °F or °C). Configure in a variety of measurement wavelengths based on target materials, process temperature ranges, and working distances from 3.9 in (100 mm) to 118.1 in (3000 mm). Available temperature ranges are: 122°F (50°C) to 2912°F (1600°C). Use up to four measurement channels with separate optical sensors connected by fiber optic cables.


  • Improves temperature measurement accuracy for critical processes
  • Enhances repeatability and minimizes variation
  • Increases productivity, yield, and throughput
  • Increases stability and reliability across multiple chambers and substrate materials
  • Customizes to meet the functional and mechanical requirements of unique applications


  • In-situ, non-contact temperature measurement employing lensed optical sensors or sapphire light pipe sensors
  • Industry-leading temperature and read rates
  • Highly flexible, module-based platform architecture
  • Full I/O and external trigger/synchronization suite
