Best Practices for Temperature Monitoring Systems
By: CAS DataLoggers
Initial Setup & Configuration
Choose a sample rate that reflects the potential for your refrigerator/
Temperature Probe Placement
The position of the probe in the storage cavity is important, as it measures the temperature at a single point in space. That point should be where it best reflects the temperatures of the material in the refrigerator or freezer. If the refrigerator cools by forced air, having the probe in the airflow will yield more fluctuations than if it is in a still area of the refrigerator.
Test the Alarms
You should test the function of the alarms before you rely on them. You need to ensure that the e-mail addresses and phone numbers for text messages or voice calls are actually received. Catching a mistyped character during configuration can prevent a loss in the future.
Review the Operation of Your System
In the early stages of using a temperature monitoring system, the data should be reviewed more frequently than a system that has been in place for many years. You need to determine that the system is operating and functioning as you require. This means data is getting recorded as desired (sample rate). The data being recorded is meaningful and accurately represents what the stored material is experiencing. Do you see fluctuations in the measured temperature or is the reading unchanged no matter what is happening with the door to the refrigerator?
