- Will the selection of the data logger impact the results of the temperature mapping study?
- Could a freezer pass with one data logger type and fail with another?
We selected various calibrated data loggers with internal and external probes and placed them adjacent to each other in a -20°C Freezer. The graph below shows a snapshot of the results, comparing an external sensor logger to an internal sensor logger.
If you’re writing a risk assessment into the temperature mapping of your controlled temperature environments, consideration should be given to the sensors used to perform the mapping. Will the buffering effect of internal sensor impact the accuracy of your mapping exercise?
