Testo Saveris 2-T1 WiFi data logger with display and Integrated NTC Temperature Probe

The WiFi data logger testo Saveris 2-T1 allows you to monitor the temperatures in refrigerated, work- or storerooms. The temperature values measured with the integrated probe are reliably recorded over long periods, and transmitted directly to the Testo Cloud (online data store) via your wireless LAN. You can access these readings anytime, anywhere, using your internet-enabled smartphone, tablet, or PC.

  • Automated temperature monitoring with integrated probe
  • WiFI data logger system with easy installation and operation
  • Call up temperature data at any time via Smartphone, tablet, or PC
  • Limit value violation alarms by e-mail or (optionally) SMS

How It Works

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.

Testo Cloud

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.


Current measuring values, limit value violations and the remaining battery life can be seen in the data logger’s display. The standard batteries (AA) have a lifetime of 12 months and can be replaced at any time by users themselves. The internal data memory of the WiFi data logger is 10,000 readings and the housing has IP65 protection. The testo Saveris 2-T1 is tested by TÜV Süd according to EN 12830.
