THE Escort iLog logger, available from Global Cold Chain Solutions , monitors vaccine fridges and provides regular, accurate readings which can be stored electronically or printed.
It indicates highest, lowest and average temperature readings and will show for how long the fridge has gone outside the set parameters. The logger is hung outside the fridge and the probe placed inside a vaccine box within the fridge.
The user later detaches the probe from the logger and leaves in the fridge, places the logger in its cradle, and downloads the readings onto computer. The software will chart the readings and a can be converted into a line graph.
An audible alarm and flashing red light can be set for readings that go above or below specification. This allows the user to take corrective action and may prevent mass vaccine wastage.
