Fluke Calibration 5628-12-L Temperature Probe

The Fluke Calibration 5628-12-L is a 25.5 ohm high-temperature platinum resistance probe for calibration work up to the aluminum point. Its 305 mm (12 inch) length and protected sensor design support use in block calibrators, furnaces, and high-temperature reference applications.

Key specifications

• Temperature range: -200 °C to 661 °C
• Nominal resistance: 25.5 ohms
• 305 mm (12 inch) probe
• Meets ITS-90 requirements for resistance ratios
• RTP drift below 20 mK after 500 hours at 660 °C
• Strain-free sensor design developed by Hart Scientific SPRT engineers
• Internal protection helps reduce platinum contamination at high temperature

Recommended applications

Use it as a working or check standard with block calibrators, furnaces, and temperature points above normal PRT temperatures. Handle and configure the probe according to the calibration system requirements.
