Data loggers with alert capability
These data loggers will record the temperature inside your medical refrigerator or laboratory freezer. They can notify you if the temperature inside the fridge or freezer goes outside of the required temperature range. These data loggers can send out an SMS and/or email to multiple people. To do this, the data loggers need to connect to the internet. Some connect to the internet through a WiFi connection while others use a Simcard to connect to a mobile phone network.
A WiFi compatible datalogger is an affordable option with little or no ongoing costs. The downside is that these can’t connect to the internet during a power outage unless the modem and NBN connection have battery back up.
A data logger that uses a mobile phone network is more expensive to operate due to the ongoing costs of a Simcard. The upside is that they will still function during a power outage.
