Vaccine transportation needs the right chip
Keeping heat-sensitive vaccines cooled at the right temperature is crucial to keep them efficacious / The demands on reliable cooling systems during transportation are correspondingly high, as are the requirements of their temperature sensors

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.
