The Onyx™-S2C is a two-color ratio, non-contact infrared optical temperature pyrometer that measures infrared energy being emitted from an object at two complementary wavelengths and converts these into usable temperature data (degrees °F or °C). Configure in a variety of measurement wavelengths based on target materials, required process temperatures, and working distances from 3.9 in (100 mm) to 118.1 in (3000 mm). The available temperature range is: 1112°F (600°C) to 2912°F (1600°C). Optional accessories include a water-cooling jacket, air-purge shower to protect against lens contamination, and mounting accessories.


  • Provides precise temperature measurement, even under harsh operating conditions
  • Integrates with a PLC/PAC for closed-loop control of critical thermal processes
  • Improves product quality by precisely controlling temperatures that affect material properties
  • Increases product throughput by increasing heat ramping efficiency and dwell times
  • Decreases energy costs through more efficient energy use (fuel or electricity)


  • Two-color ratio measurement, for changing emissivity or view path obstructions (such as smoke or steam)
  • Precise measurement for moving, rotavating, or inaccessible work pieces, or when direct physical contact would damage the work product
  • Integrated laser or optical alignment for easy installation and alignment
  • Non-contact device, providing years of service without interruption, requiring minimal maintenance or re-calibration
  • Optional Rockwell Automation® Add-on Profiles (AOPs), simplifying setup and commissioning using predefined tags
