- Range to 660°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 Harts SPRT engineers
- High-temp PRT, 25.5 Ohm, 305 mm (12 in)
- If youre using block calibrators, furnaces, or temperature points above normal PRT temperatures (420 °C), then these two PRTs are for you
- The 5626 is nominally 100ohms and the 5628 is nominally 25.5 Ohms
- 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
