Basic Fridge Data Loggers
Data Loggers record temperature readings at set intervals by electronic means. The stored data can then be downloaded to a computer. Data loggers may be used for audits and to establish the recording patterns of your vaccine refrigerator over time. A fridge logger can be especially handy for determining whether a medical vaccine fridge that has exceeded 8 degrees Celsius has done so for less than the critical 15 minutes that may be permissible.
Daily minimum/maximum temperature readings will still need to be manually recorded. If you are using a data logger instead of a maximum/minimum thermometer, the data logger must have a visual max/min display so that you can record your daily max/min fridge temperatures.
The fridge loggers on this page all need to be manually downloaded. Most of the fridge loggers can be connected to the USB port of a PC either directly or by using a USB cable or USB cradle. Intemp's loggers are downloaded by using Bluetooth.
