5624 Platinum Resistance Thermometer to 1000 °C

We’re pleased to introduce the world’s finest high-temperature secondary PRT, our Model 5624.

 

5624 Platinum Resistance Thermometer with Temperature Range of 0 °C to 1000 °C

  • Temperature range of 0°C to 1000°C
  • Accuracy (includes short-term stability and calibration uncertainty) of ±0.05°C to 962°C
  • Long-term drift of 0.01°C at 0°C after 100 hours at 1000°C
  • Designed by Fluke Calibration’s primary standards design team
  • At Fluke Calibration, we receive many requests for precision PRT accuracy at thermocouple temperatures. Until now metrologist have settled for expensive, high-temperature SPRTs or inaccurate thermocouples for high-temperature measurement.We’re pleased to introduce the world’s finest high-temperature secondary PRT, our Model 5624.

The 5624 is ideal for use as a reference thermometer in high-temperature furnaces, the 5624 can reach a temperature of 1000°C with long-term drift at 0°C of 10 mK and accuracy (including short-term stability and calibration uncertainty over the full range) of 55 mK! Due to Fluke Calibration's proprietary sensor design, this PRT has short-term stability of 5 mK, and an immersion requirement of less than 153 mm (6") at 700°C.

The 5624 is assembled in an alumina sheath that is 508 mm (20") long and 6.35 mm (0.25") in diameter. Several termination configurations can be selected to match different thermometer readouts. Each 5624 comes with a NIST-traceable, NVLAP-accredited fixed-point calibration from 0°C to 962°C. That’s a fixed-point calibration! The 5624 also comes in a protective carrying case.
