The right chip for vaccine transportation to keep them efficacious

Published on : Saturday 16-01-2021

The demands on reliable cooling systems during transportation are correspondingly high, as are the requirements of their temperature sensors

January 2021 – Keeping vaccines cooled during storage and transportation requires a special RTD temperature sensor, this is why:

Different vaccine manufacturers require various storage temperatures. Some typical storage temperatures for vaccines are -20°C, others require storage at -70°C. The industry standard for thin film RTD sensors are limited to -30°C for class A and -50°C for class B, which is in conflict with this requirement.

The IST PW series is the only thin film RTD in the market that comes with a specified accuracy all the way down to negative -70°C or lower. Therefore, our PW series meets class A tolerance at the required temperatures for vaccine storage. This translates to an outstanding accuracy for thin film RTD chips of +/- 0.29°C at -70°C, which significantly exceeds the required accuracy dictated by vaccine manufacturers. This allows room for manufacturing uncertainties during probe and storage equipment assemblies and makes an expensive post-calibration unnecessary.

The PW series is offered in class B, class A, 1/3 DIN or even higher all the way to negative -200°C.
