5624 Platinum Resistance Thermometer to 1000 °C
Key features
- Operates within a temperature range of 0 °C to 1000 °C.
- Accuracy of ±0.05°C up to 962°C, which includes short-term stability and calibration uncertainty.
- Long-term drift of 0.01°C at 0°C after 100 hours at 1000°C.
- Ideal for measurements requiring precision PRT accuracy at high thermocouple temperatures, a superior alternative to expensive high-temperature SPRTs or less accurate thermocouples.
Product overview: 5624 Platinum Resistance Thermometer to 1000 °C
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.
