Testo Saveris 2-H1 WiFi Data Logger and 2 Wide Range Temperature Probes

The WiFi data logger testo Saveris 2-H1 allows you to monitor the temperatures and humidity in refrigerated and work- or storerooms. The temperature and humidity values measured with the integrated probes are reliably recorded over long periods, and transmitted directly to the Testo Cloud (online data storage) via your wireless LAN. You can access these readings at any time, anywhere, using your internet-enabled smartphone, tablet, or PC.

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

How It Works

The humidity and 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-H1 temperature and humidity data logger with integrated temperature and humidity probes stores all measured values and transmits them directly by wireless LAN 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 has a capacity of 2 x 10,000 readings and the housing is protected according to IP30.

In order to use the testo Saveris 2-T3 WiFi data logger, you also require at least one connectable thermocouple probe (optional).

In order to use the testo Saveris 2-T2 WiFi data logger, you also require at least one connectable probe (optional).
