Description
Overview
The Fluke Calibration 5626-15-B is a secondary standard platinum resistance thermometer (PRT) designed for high-temperature calibration applications. With a temperature range of -200°C to 661°C and 100 ohm nominal resistance, it provides an affordable alternative to more expensive standard platinum resistance thermometers (SPRTs). The bare wire termination offers flexibility for custom connections and measurement setups. The probe features Inconel 600 sheath construction to minimize contamination risk while maintaining reliable performance in demanding calibration environments.
