Fluke Calibration 5626
Secondary Standard PRT Temperature Sensor
Discontinued

  • Range to 660°C
  • Meets 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

Hart's high-temp secondary standards fill the gap between affordable, but temperature-limited secondary PRTs and more expensive, highly accurate SPRTs.

If you're using block calibrators, furnaces, or temperature points above normal PRT temperatures (420 °C), then this PRT is for you. The 5626 is nominally 100W and has a temperature range of -200 °C to 661 °C. 5626 makes 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 is designed to reduce the contamination risk through the use of internal protection while not impairing performance.

In addition to the right measurement performance and durability, a PRT for secondary applications should be priced affordably. Hart's new PRTs are inexpensive and come with an accredited calibration. The calibration comes complete with ITS-90 constants and a resistance-versus-temperature table.

Check the temperature range, check the stability, check the price! Who else gives you this much quality, performance, and value for your money? No one!
