Fluke Calibration 5626-15-A High-Temp PRT Probe, 100 Ohm, 381 mm, -200 to 661°C

The Fluke Calibration 5626-15-A is a high-temperature platinum resistance thermometer (PRT) probe, 100 Ω, 381 mm long, with a range of -200 °C to 661 °C. Designed for use in block calibrators and furnaces, it meets ITS-90 requirements and offers excellent stability with minimal drift.

Key Features & Highlights

• Temperature range from -200 °C to 661 °C
• Nominal resistance of 100 Ω at 0 °C
• Probe length: 381 mm (15 in)
• Meets all ITS-90 requirements for resistance ratios
• Resistance drift < 20 mK after 500 hours at 660 °C
• Strain-free sensor design by Hart SPRT engineers
• Reduced contamination risk through internal protection

Applications

Ideal for use as a working or check standard in calibration laboratories, especially for temperature measurements above 420 °C. Suitable for block calibrators, furnaces, and calibration up to the aluminum point. The 5626-15-A provides a robust alternative to more delicate SPRTs, offering high performance with reduced risk of damage.
