The testo Saveris 2 WiFi data logger system is the easy, versatile and reliable solution for the measurement and monitoring of temperature values in your storage, refrigerated and work rooms. Installing the system is child’s play and can be carried out either via a browser or with the testo Saveris 2 App.
Temperature monitoring with testo Saveris 2
The temperature monitoring system consists of at least one WiFi data logger and a Cloud access (online data store). As a component of this data logger system, the testo Saveris 2-T1 temperature data logger with integrated NTC temperature probe stores all measured temperature values and transmits them directly via your WLAN to the Testo Cloud. You can use the alarm function to receive immediate warnings by e-mail or SMS (optional) when limit values are violated.
The Testo Cloud packages: Basic (free) and Advanced
The Testo Cloud is the core operating element for setting up your testo Saveris 2 system. Here you can configure your WiFi data loggers, set limit value alarms and analyze your measurement data. You can access all measuring values and analysis functions anywhere and at any time with an internet-capable smartphone, tablet or PC. You must first register at www.saveris.net to have access to the Testo Cloud.
