Fluke Calibration 5626-15-P Secondary PRT Probe, 100 ohm 1/4" Diameter x 15"

Product Highlights

• Seconday Standard PRT, 100Ω, 381 mm (15 in)
• Range to 661°C
• Meets all ITS-90 reMeets all ITS-90 requirements for resistance ratios
• Rtp drift < 20mK after 500 hours at 660°C
• Strain-free sensor design by Hart's SPRT engineers
• If you're using block calibrators, furnaces, or temperature points above normal PRT temperatures (420 °C), then these two PRTs are for you
• The 5626 is nominally 100Ω and the 5628 is nominally 25.5 Ohm
• Both instruments have a temperature range of -200 °C to 661 °C
• They make great working or check standards for calibration work up to the aluminum point
• Using a regular PRT at temperatures above 500 °C exposes the platinum to contamination
• If the PRT is used as a reference or calibration standard, contamination is a major problem
• SPRTs, which are more expensive and delicate, can handle the higher temperatures, but with greater risk to the instrument due to shock, contamination, or mishandling
• The 5626 and 5628 are designed to reduce the contamination risk through the use of internal protection while not impairing performance
