The WiFi data logger testo Saveris 2-T2 allows you to monitor the temperatures and door contacts in refrigerated and work- or storerooms. The temperature values and door contacts measured with the connectable probes are reliably recorded over long periods, and transmitted directly to the Testo Cloud (online data store) via your WiFi. You can access these readings at any time, anywhere, using your internet-enabled smartphone, tablet or PC.

Features

• Automated door contact and temperature monitoring with connectable probes (optional).
• 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
