hi, My question is, how does this product work? I am looking for a way to log the temperature of our server room for at least 24 hours. can i just put the Elpro Libero Temperature Datalogger into the server room so it can measure the temperature or do

The Libero is designed for long term monitoring. It will not send alerts, though it will indicate on its LCD screen if the maximum temperature has been exceeded. Typical use would be in a truck recording the temperature of a delivery. The receiver would check to see if the maximum temperature has been exceeded and make a ito accept or reject the delivery. When the Libero is plugged inot a PC with a USB socket it generates a PDF file showing all the recorded temperatures. The Libero comes with software to set thresholds and to allow the unit to be reset for the next trip.

Devices such as the SensorProbe2 are designed for fixed installations and are part of your IP network. These units can send email alerts if the temperature thresholds are exceeded.
