Sekidenko OR4000T


Multi-Channel, Non-Contact Optical Fiber Temperature Pyrometer with Configurable Wavelength Range and Fixed-Emissivity Correction

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.
