The WiFi data logger testo Saveris 2-T3 allows you to monitor the temperatures in processes or in refrigerated and work- or storerooms. The temperature values measured with the connectable thermocouple probes (TC) are reliably recorded over long periods, and transmitted directly to the Testo Cloud (online data storage) via your WiFi. You can access these readings at any time, anywhere, using your internet-enabled smartphone, tablet or PC.

Features

• Broad measuring range of -195 to +1350 °C possible thanks to 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
