All Dulas refrigerators are fitted with 30 day temperature loggers as standard. The fridge-tag is a high precision temperature data logger for the continuous monitoring of sensitive vaccines. It sits inside the fridge and monitors temperatures.  It automatically triggers an alarm if a critical temperature deviation outside the predefined temperature range is measured. Data can be downloaded locally via the USB.
