The Cryo-con line of Platinum RTDs include:

• The CP-100 ceramic wire-wound RTD.
• GP-100 glass platinum band RTD.
• XP-100 thin-film RTD.

Temperature ranges are 14K to 873K. Temperatures below 20K require special calibrations.

Nominal resistance is 100 Ohms at 0°C. Two and three-point critical temperature calibrations are available.

Conformance to DIN and IEC standard calibration curves.

Cryogenically conditioned for highest accuracy at low temperature.
