The Sekidenko OR4000E is a multi-channel, non-contact optical fiber temperature pyrometer that measures infrared energy emitted from an object and converts it into usable temperature data (degrees °F or °C). Real-time emissivity measurement and compensation precisely compensates for a material’s change in emissivity during processing. 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). You can use one or two measurement channels with separate optical sensors connected by fiber optic cables.


  • Improves temperature-measurement accuracy for critical processes
