The Ultra Cold Temperature Sensor is suitable for monitoring a wider range of temperatures from -200°C to 150°C (-328°F to 302°F). It is used for ultra-cold shipments or storage, such as for the mRNA-based COVID-19 vaccines from Pfizer and Moderna.

Based on an RTD type sensor (Resistance Temperature Detector) made from platinum, this sensor precisely measures changes in the resistance of the metal to give an accuracy reading of ±0.2°C (±0.4°F).

This sensor is compatible with the  (SP ) platform only.
