Temperature measurements

Platinum-rhodium thermocouples

Range: 0 °C to 1800 °C

Supply of bespoke thermocouples

NPL’s Pt-Rh thermocouples are constructed in-house, and may be modified to meet end-user requirements. They are offered with a full UKAS (ISO 17025) accredited calibration. They are constructed from wires (0.5 mm in diameter and typically 2 m in length) in an alumina insulator (typically 0.7 m long). The thermocouples can be purchased with or without cold-junction attachments to copper extension leads.

Calibration

The calibration uncertainty (k = 2) can be as low as ±0.3 °C over the range 0 °C to 1100 °C, rising to ±0.55 °C at 1330 °C, ±0.72 °C at 1500 °C, and ±1.2 °C at 1800 °C.
