Sekidenko 4100T Series


Multi-Channel, Non-Contact Optical Fiber Temperature Pyrometer with Configurable Wavelength Range

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.
