The EL-USB-ULT is designed to monitor vaccines in cryogenic dry ice storage. This standalone data logger measures and stores more than 32,000 temperature readings from its high accuracy thermocouple temperature probe.

The user can easily set up the logger and view downloaded data by plugging the data logger into a PC’s USB port and using the free EasyLog software. Data can then be graphed, printed and exported to other applications for detailed analysis. The data logger is supplied with a lithium metal battery which typically gives 2 years’ logging life.
