Product Integrity Profile (PIP)
|Contents Previous Next|
A frequent use of Temprecord data loggers is to monitor the temperature of a shipment with passive refrigeration, i.e where cooling of the product is achieved by adding refrigerated ballast such as ice packs to the consignment. The temperature profile thus starts off at a relatively higher temperature, falls to a minimum, then warms back to ambient. The goal is to ensure the product cools quickly and remains in the safe storage temperature zone for the anticipated duration of the journey. Blood products tend to use this type of refrigeration where the container is made from expanded polystyrene foam.
If a Temprecord logger is included with the shipment, the Temprecord program provides the ability to quickly analyse a temperature record and determine key indicators via the Product Integrity Profile. The information is presented in the form of annotations on the graph, and a report as part of the statistics. Both of these functions can be enabled with the Show Product Integrity Statistics option.
The start sample sets the start position of the PIP analysis. The end sample sets the end position. For a logger or file that has just been read the start and end samples are set to the first and last samples. This may be appropriate or you can change them at any time, and the PIP statistics will be recalculated and displayed for the data between the new start and end samples.
The upper temperature limit sets the upper boundary of the cool zone and the lower temperature limit the lower boundary. For a logger or file that has just been read these limits are set to the limits the logger was programmed with. You can change the limits at any time, and the PIP statistics will be recalculated and displayed for the new upper and lower limits.
In the example below, the upper and lower limits are set to 10C and 2.3C, and the start and end samples are set to the first and last samples.
