What do we measure where?From fridge to stability chamber
Measurement points are selected based on use locations, airflow, door use, loading and acceptance criteria.
Laboratory fridgeShelves, door zone, back wall, loading and sensor position.Assessment of suitable storage zones for 2-8 °C or product-specific limits.
-20 °C freezerDrawers, door influence, recovery, loading and temperature distribution.Substantiation of storage locations and monitoring position.
-80 °C freezerRacks, boxes, door zones, recovery after opening and temperature gradients.Insight into worst-case zones for critical samples.
IncubatorSample locations, shelves, air circulation and stability.Assessment whether used positions are suitable for the method.
Stability or climate chamberTemperature, possibly RH, shelf locations and loading pattern.Substantiation of uniformity and stability for intended use.
