WiFi Temperature Data Logger

The A2-05-W WiFi Temperature Data Logger is designed for high-accuracy temperature measurement and alarm in medical refrigerators, freezers, cryogenic storage and incubators.

The data logger has connections for 2 external RTDs and a Thermocouple sensor making it incredibly cost effective for multi-point monitoring. In the event of a network connection loss, the data logger will send Automatic Power or Internet outage alarms and store data until the connection is restored.

Using a standard WiFi connection to the internet, the wireless data logger quickly connects to your WiFi network.

We also offer a Wired Ethernet version of this model for LAN-based temperature monitoring.
