Description
Overview
The Fluke Calibration 5626-12-S 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 solution that bridges the gap between temperature-limited secondary PRTs and more expensive standard platinum resistance thermometers (SPRTs). The probe features Inconel 600 sheath construction to minimize contamination risk while maintaining measurement performance.
Key Features
- Secondary standard PRT with 100 ohm nominal resistance (±1 ohm)
- Temperature range of -200°C to 661°C
- 12-inch (304.8 mm) sheath length with 1/4 inch (6.35 mm) diameter
- Inconel 600 sheath material for durability and contamination resistance
- 4-wire Super-Flex PVC lead wires (22 AWG)
- Spade lug termination
- Meets ITS-90 requirements for resistance ratios
- Minimum 5-inch (12.7 cm) immersion depth recommended
Applications
- Block calibrator and furnace calibration
- Temperature calibration up to aluminum point (661°C)
- Working or check standard for secondary calibration work
- High-temperature measurement in laboratory and industrial settings
