The Sekidenko 4100T multi-channel, non-contact optical fiber temperature pyrometer measures an object’s emitted infrared energy and converts it into usable temperature data (degrees °F or °C) with temperature ranges between 60 to 3500°C (140 to 6332°F). The pyrometer is configurable to a variety of measurement wavelengths based on target materials, process temperature ranges, and working distances. The multi-channel feature allows for use of up to four measurement channels with separate optical sensors connected by fiber optic cables. The new touch screen display enables users to easily adjust settings without the need for a laptop.


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


  • 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
  • Multiple wavelengths within one instrument
