Raytek Endurance Series of high-temperature infrared pyrometers by Fluke Process Instruments is engineered to seamlessly integrate with major control systems in modern industries. Available in single-color, two-color, and fiber optic models, these pyrometers are designed to be flexible and easy to install. They are built to withstand harsh industrial environments, offering visual temperature data to enhance process understanding.

Featuring optional integrated cameras for continuous visual monitoring and LED sighting for precise targeting, these pyrometers eliminate the guesswork in setting emissivity. The fiber-optic models allow measurement of otherwise inaccessible targets, using a flexible cable to position the optical head close to the target while keeping rugged electronics safely remote. These sensors are non-conductive, providing improved immunity to interference.

The Endurance Series includes companion software for archiving temperature data and sensor configuration, catering to the needs of Digital Industry. With a robust stainless steel housing, these pyrometers support a wide range of communication interfaces from analog to LAN/Ethernet and RS485, ensuring reliable communication with control systems and monitoring stations. Backed by a best-in-class 4-year warranty, the Endurance Series is designed for accurate temperature measurement in the toughest environments.
